| 10 | - <Description>The primary task of this instrument (PEACE: Plasma Electrons and Currents Experiment) | ||
| 11 | - is to obtain the velocity moments of the distribution function of electrons as frequently and | ||
| 12 | - as accurately as the spacecraft telemetry will allow. Detector counts are collected in energy, | ||
| 13 | - polar-angle, and azimuth-angle bins to form a three-dimensional matrix. | ||
| 14 | - Two sensors are used: LEEA (low-energy electron analyzer) and HEEA (high-energy electron analyzer). | ||
| 15 | - The energy coverage is from 0.67 eV to 30 KeV in 92 levels. The first 16 levels are equally spaced linearly | ||
| 16 | - up to 10.7 eV; the remainder are logarithmically spaced. Both sensors can use the full range, but the HEEA | ||
| 17 | - will normally operate over a higher energy range than the LEEA. The LEEA specializes in coverage of the | ||
| 18 | - energies from 0.7-10 eV, and has a geometric factor one fifth that of the HEAA. Both sensors consist of | ||
| 19 | - hemispherical electrostatic analyzers of the top-hat type and a detector in the form of an annular | ||
| 20 | - micro-channel plate with a position-sensitive readout. Each sensor covers the range 0-180 degrees | ||
| 21 | - with respect to the spin axis, and they are mounted opposite each other with a view perpendicular | ||
| 22 | - to the spin axis, thus covering the complete angular range in a half rotation of the spacecraft. | ||
| 23 | - The field of view perpendicular to the fan is 2 degrees for the LEEA and 5.6 degrees for the HEEA. | ||
| 24 | - Energy resolution (Delta-E)/E is 0.13 for LEEA and 0.16 for HEEA. There are four sweep modes, | ||
| 25 | - synchronized to the spin period (4 s), to vary the azimuthal angular resolution. | ||
| 26 | - The spin phasing can be made coincident with that of the CIS instrument, to ensure that the electron | ||
| 27 | - and ion moments will be measured simultaneously. On-board processing is used to calculate the moments | ||
| 28 | - of the distribution with an accuracy of 1% and to select suitable parts of the complete distribution | ||
| 29 | - for transmission. The normal science data format is based on one spin period, and consists of core data | ||
| 30 | - followed by other optional distributions as can be fit into the available telemetry for that spin. | ||
| 31 | - The core data (moments, spacecraft potential, and pitch angle distribution) are always transmitted | ||
| 32 | - (if the spin is nominal). The next distribution is transmitted if, before the end of the spin, | ||
| 33 | - all the previous data have been sent. Thus the next spin of data will be transmitted slightly late, | ||
| 34 | - but all of its core data will be transmitted before the following spin of data is started on. | ||
| 35 | - Eventually the transmission will catch up and be able to transmit the distribution after the core again, | ||
| 36 | - but only after some time. This applies at all telemetry rates. The instrument can adapt automatically to | ||
| 37 | - six different telemetry rates: a basic 1.52 Kbps rate (CIS priority); a normal 2.52 Kbps rate; | ||
| 38 | - an enhanced PEACE priority rate of 3.54 Kbps; and three burst mode rates, with a maximum of 15.98 Kbps. | ||
| 39 | - For more details of the Cluster mission, the spacecraft, and its instruments, | ||
| 40 | - see the report Cluster: mission, payload and supporting activities, March 1993, ESA SP-1159, | ||
| 41 | - and the included article PEACE: a Plasma Electron and Current Experiment, by A. D. Johnstone et al., | ||
| 42 | - from which this information was obtained.</Description> | ||

| 10 | + <Description> The CAA Moments data are electron density, velocity vector, | ||
| 11 | + pressure tensor and heat flux vector. The vectors and tensors are provided in GSE coordinates. Velocity and temperature | ||
| 12 | + are also provided as components perpendicular and parallel to the magnetic field. | ||
| 13 | + The magnetic field data is taken from CSDS FGM PP data, at present. In a possible future | ||
| 14 | + release we would ideally use CAA FGM data, but it is considered unlikely that there will be major differences except in | ||
| 15 | + very weak field regions. Furthermore : | ||
| 16 | + * T_perp and T_para are determined by projecting the pressure tensor along the magnetic field and dividing by the density and by Boltzmanns constant. T_perp is the average of the two perpendicular components. | ||
| 17 | + * v_para = (v.b) b and v_perp = v - (v.b) b. where v is the velocity vector and b is the magnetic field unit vector. | ||
| 18 | + | ||
| 19 | + These data are produced on the ground using 3-D data and thus are available at time resolutions which are limited by the | ||
| 20 | + rate at which 3-D data can be transmitted. The data source used to generate the mome | ||
| 21 | + nts is always the best available resolution 3-D data; this means mainly 3DR data but in the case 3DX or 3DXP are available these | ||
| 22 | + are used instead for the MOMENTS production (see Mode_DataOrigin_HEEA/LEEA). Choices on the best way to combine data from the two | ||
| 23 | + sensors can be made in the moments production software; in the first release the moments are made using LEEA data in the | ||
| 24 | + energy overlap region. | ||
| 25 | + In some situations, use of both sensors together may be a better choice, for example in case | ||
| 26 | + s where the distribution changes | ||
| 27 | + during a spin as the method can resolve time aliasing errors. If resources allow, the Moments | ||
| 28 | + product at CAA may be updated to take advantage of this possibility. | ||
| 29 | + The advantage of these ground - calculated moments is that the best available | ||
| 30 | + calibration data is used, a correction can be made for the spacecraft potential | ||
| 31 | + measurements (collected by the EFW experiment), and spacecraft electrons can be | ||
| 32 | + properly removed. The current release has been generated automatically | ||
| 33 | + using default values to control the approach to | ||
| 34 | + potential correction and photoelectron removal, and has not been systematically human | ||
| 35 | + - validated, so some errors may exist. | ||
| 36 | + Specifically, the spacecraft potential, Vsc, is set to be 1 V greater than the | ||
| 37 | + measured probe - spacecraft potential provided by | ||
| 38 | + the electric field experiment (EFW) and the lower energy cutoff for the moments | ||
| 39 | + integration is set to reject the energy bin | ||
| 40 | + containing the EFW potential and the one above that (which in practice | ||
| 41 | + may also contain counts due to spacecraft electrons). | ||
| 42 | + Sometimes cold electrons are present which can appear in the same energy bin as the spacecraft photoelectrons, | ||
| 43 | + therefore both the cold electrons and spacecraft photoelectrons are removed resulting in underestimated electron densities. | ||
| 44 | + Recent work | ||
| 45 | + by the EFW team suggests a more accurate determination of from would be a term that increases linearly | ||
| 46 | + above ~10 V (Cully et al., 2007) but this has not yet been | ||
| 47 | + implemented in our CAA moments generation code.</Description> | ||

| 10 | - <Description>The primary task of this instrument (PEACE: Plasma Electrons and Currents Experiment) | ||
| 11 | - is to obtain the velocity moments of the distribution function of electrons as frequently and | ||
| 12 | - as accurately as the spacecraft telemetry will allow. Detector counts are collected in energy, | ||
| 13 | - polar-angle, and azimuth-angle bins to form a three-dimensional matrix. | ||
| 14 | - Two sensors are used: LEEA (low-energy electron analyzer) and HEEA (high-energy electron analyzer). | ||
| 15 | - The energy coverage is from 0.67 eV to 30 KeV in 92 levels. The first 16 levels are equally spaced linearly | ||
| 16 | - up to 10.7 eV; the remainder are logarithmically spaced. Both sensors can use the full range, but the HEEA | ||
| 17 | - will normally operate over a higher energy range than the LEEA. The LEEA specializes in coverage of the | ||
| 18 | - energies from 0.7-10 eV, and has a geometric factor one fifth that of the HEAA. Both sensors consist of | ||
| 19 | - hemispherical electrostatic analyzers of the top-hat type and a detector in the form of an annular | ||
| 20 | - micro-channel plate with a position-sensitive readout. Each sensor covers the range 0-180 degrees | ||
| 21 | - with respect to the spin axis, and they are mounted opposite each other with a view perpendicular | ||
| 22 | - to the spin axis, thus covering the complete angular range in a half rotation of the spacecraft. | ||
| 23 | - The field of view perpendicular to the fan is 2 degrees for the LEEA and 5.6 degrees for the HEEA. | ||
| 24 | - Energy resolution (Delta-E)/E is 0.13 for LEEA and 0.16 for HEEA. There are four sweep modes, | ||
| 25 | - synchronized to the spin period (4 s), to vary the azimuthal angular resolution. | ||
| 26 | - The spin phasing can be made coincident with that of the CIS instrument, to ensure that the electron | ||
| 27 | - and ion moments will be measured simultaneously. On-board processing is used to calculate the moments | ||
| 28 | - of the distribution with an accuracy of 1% and to select suitable parts of the complete distribution | ||
| 29 | - for transmission. The normal science data format is based on one spin period, and consists of core data | ||
| 30 | - followed by other optional distributions as can be fit into the available telemetry for that spin. | ||
| 31 | - The core data (moments, spacecraft potential, and pitch angle distribution) are always transmitted | ||
| 32 | - (if the spin is nominal). The next distribution is transmitted if, before the end of the spin, | ||
| 33 | - all the previous data have been sent. Thus the next spin of data will be transmitted slightly late, | ||
| 34 | - but all of its core data will be transmitted before the following spin of data is started on. | ||
| 35 | - Eventually the transmission will catch up and be able to transmit the distribution after the core again, | ||
| 36 | - but only after some time. This applies at all telemetry rates. The instrument can adapt automatically to | ||
| 37 | - six different telemetry rates: a basic 1.52 Kbps rate (CIS priority); a normal 2.52 Kbps rate; | ||
| 38 | - an enhanced PEACE priority rate of 3.54 Kbps; and three burst mode rates, with a maximum of 15.98 Kbps. | ||
| 39 | - For more details of the Cluster mission, the spacecraft, and its instruments, | ||
| 40 | - see the report Cluster: mission, payload and supporting activities, March 1993, ESA SP-1159, | ||
| 41 | - and the included article PEACE: a Plasma Electron and Current Experiment, by A. D. Johnstone et al., | ||
| 42 | - from which this information was obtained.</Description> | ||

| 10 | + <Description> The CAA Moments data are electron density, velocity vector, | ||
| 11 | + pressure tensor and heat flux vector. The vectors and tensors are provided in GSE coordinates. Velocity and temperature | ||
| 12 | + are also provided as components perpendicular and parallel to the magnetic field. | ||
| 13 | + The magnetic field data is taken from CSDS FGM PP data, at present. In a possible future | ||
| 14 | + release we would ideally use CAA FGM data, but it is considered unlikely that there will be major differences except in | ||
| 15 | + very weak field regions. Furthermore : | ||
| 16 | + * T_perp and T_para are determined by projecting the pressure tensor along the magnetic field and dividing by the density and by Boltzmanns constant. T_perp is the average of the two perpendicular components. | ||
| 17 | + * v_para = (v.b) b and v_perp = v - (v.b) b. where v is the velocity vector and b is the magnetic field unit vector. | ||
| 18 | + | ||
| 19 | + These data are produced on the ground using 3-D data and thus are available at time resolutions which are limited by the | ||
| 20 | + rate at which 3-D data can be transmitted. The data source used to generate the mome | ||
| 21 | + nts is always the best available resolution 3-D data; this means mainly 3DR data but in the case 3DX or 3DXP are available these | ||
| 22 | + are used instead for the MOMENTS production (see Mode_DataOrigin_HEEA/LEEA). Choices on the best way to combine data from the two | ||
| 23 | + sensors can be made in the moments production software; in the first release the moments are made using LEEA data in the | ||
| 24 | + energy overlap region. | ||
| 25 | + In some situations, use of both sensors together may be a better choice, for example in case | ||
| 26 | + s where the distribution changes | ||
| 27 | + during a spin as the method can resolve time aliasing errors. If resources allow, the Moments | ||
| 28 | + product at CAA may be updated to take advantage of this possibility. | ||
| 29 | + The advantage of these ground - calculated moments is that the best available | ||
| 30 | + calibration data is used, a correction can be made for the spacecraft potential | ||
| 31 | + measurements (collected by the EFW experiment), and spacecraft electrons can be | ||
| 32 | + properly removed. The current release has been generated automatically | ||
| 33 | + using default values to control the approach to | ||
| 34 | + potential correction and photoelectron removal, and has not been systematically human | ||
| 35 | + - validated, so some errors may exist. | ||
| 36 | + Specifically, the spacecraft potential, Vsc, is set to be 1 V greater than the | ||
| 37 | + measured probe - spacecraft potential provided by | ||
| 38 | + the electric field experiment (EFW) and the lower energy cutoff for the moments | ||
| 39 | + integration is set to reject the energy bin | ||
| 40 | + containing the EFW potential and the one above that (which in practice | ||
| 41 | + may also contain counts due to spacecraft electrons). | ||
| 42 | + Sometimes cold electrons are present which can appear in the same energy bin as the spacecraft photoelectrons, | ||
| 43 | + therefore both the cold electrons and spacecraft photoelectrons are removed resulting in underestimated electron densities. | ||
| 44 | + Recent work | ||
| 45 | + by the EFW team suggests a more accurate determination of from would be a term that increases linearly | ||
| 46 | + above ~10 V (Cully et al., 2007) but this has not yet been | ||
| 47 | + implemented in our CAA moments generation code.</Description> | ||

| 10 | - <Description>The primary task of this instrument (PEACE: Plasma Electrons and Currents Experiment) | ||
| 11 | - is to obtain the velocity moments of the distribution function of electrons as frequently and | ||
| 12 | - as accurately as the spacecraft telemetry will allow. Detector counts are collected in energy, | ||
| 13 | - polar-angle, and azimuth-angle bins to form a three-dimensional matrix. | ||
| 14 | - Two sensors are used: LEEA (low-energy electron analyzer) and HEEA (high-energy electron analyzer). | ||
| 15 | - The energy coverage is from 0.67 eV to 30 KeV in 92 levels. The first 16 levels are equally spaced linearly | ||
| 16 | - up to 10.7 eV; the remainder are logarithmically spaced. Both sensors can use the full range, but the HEEA | ||
| 17 | - will normally operate over a higher energy range than the LEEA. The LEEA specializes in coverage of the | ||
| 18 | - energies from 0.7-10 eV, and has a geometric factor one fifth that of the HEAA. Both sensors consist of | ||
| 19 | - hemispherical electrostatic analyzers of the top-hat type and a detector in the form of an annular | ||
| 20 | - micro-channel plate with a position-sensitive readout. Each sensor covers the range 0-180 degrees | ||
| 21 | - with respect to the spin axis, and they are mounted opposite each other with a view perpendicular | ||
| 22 | - to the spin axis, thus covering the complete angular range in a half rotation of the spacecraft. | ||
| 23 | - The field of view perpendicular to the fan is 2 degrees for the LEEA and 5.6 degrees for the HEEA. | ||
| 24 | - Energy resolution (Delta-E)/E is 0.13 for LEEA and 0.16 for HEEA. There are four sweep modes, | ||
| 25 | - synchronized to the spin period (4 s), to vary the azimuthal angular resolution. | ||
| 26 | - The spin phasing can be made coincident with that of the CIS instrument, to ensure that the electron | ||
| 27 | - and ion moments will be measured simultaneously. On-board processing is used to calculate the moments | ||
| 28 | - of the distribution with an accuracy of 1% and to select suitable parts of the complete distribution | ||
| 29 | - for transmission. The normal science data format is based on one spin period, and consists of core data | ||
| 30 | - followed by other optional distributions as can be fit into the available telemetry for that spin. | ||
| 31 | - The core data (moments, spacecraft potential, and pitch angle distribution) are always transmitted | ||
| 32 | - (if the spin is nominal). The next distribution is transmitted if, before the end of the spin, | ||
| 33 | - all the previous data have been sent. Thus the next spin of data will be transmitted slightly late, | ||
| 34 | - but all of its core data will be transmitted before the following spin of data is started on. | ||
| 35 | - Eventually the transmission will catch up and be able to transmit the distribution after the core again, | ||
| 36 | - but only after some time. This applies at all telemetry rates. The instrument can adapt automatically to | ||
| 37 | - six different telemetry rates: a basic 1.52 Kbps rate (CIS priority); a normal 2.52 Kbps rate; | ||
| 38 | - an enhanced PEACE priority rate of 3.54 Kbps; and three burst mode rates, with a maximum of 15.98 Kbps. | ||
| 39 | - For more details of the Cluster mission, the spacecraft, and its instruments, | ||
| 40 | - see the report Cluster: mission, payload and supporting activities, March 1993, ESA SP-1159, | ||
| 41 | - and the included article PEACE: a Plasma Electron and Current Experiment, by A. D. Johnstone et al., | ||
| 42 | - from which this information was obtained.</Description> | ||

| 10 | + <Description> The CAA Moments data are electron density, velocity vector, | ||
| 11 | + pressure tensor and heat flux vector. The vectors and tensors are provided in GSE coordinates. Velocity and temperature | ||
| 12 | + are also provided as components perpendicular and parallel to the magnetic field. | ||
| 13 | + The magnetic field data is taken from CSDS FGM PP data, at present. In a possible future | ||
| 14 | + release we would ideally use CAA FGM data, but it is considered unlikely that there will be major differences except in | ||
| 15 | + very weak field regions. Furthermore : | ||
| 16 | + * T_perp and T_para are determined by projecting the pressure tensor along the magnetic field and dividing by the density and by Boltzmanns constant. T_perp is the average of the two perpendicular components. | ||
| 17 | + * v_para = (v.b) b and v_perp = v - (v.b) b. where v is the velocity vector and b is the magnetic field unit vector. | ||
| 18 | + | ||
| 19 | + These data are produced on the ground using 3-D data and thus are available at time resolutions which are limited by the | ||
| 20 | + rate at which 3-D data can be transmitted. The data source used to generate the mome | ||
| 21 | + nts is always the best available resolution 3-D data; this means mainly 3DR data but in the case 3DX or 3DXP are available these | ||
| 22 | + are used instead for the MOMENTS production (see Mode_DataOrigin_HEEA/LEEA). Choices on the best way to combine data from the two | ||
| 23 | + sensors can be made in the moments production software; in the first release the moments are made using LEEA data in the | ||
| 24 | + energy overlap region. | ||
| 25 | + In some situations, use of both sensors together may be a better choice, for example in case | ||
| 26 | + s where the distribution changes | ||
| 27 | + during a spin as the method can resolve time aliasing errors. If resources allow, the Moments | ||
| 28 | + product at CAA may be updated to take advantage of this possibility. | ||
| 29 | + The advantage of these ground - calculated moments is that the best available | ||
| 30 | + calibration data is used, a correction can be made for the spacecraft potential | ||
| 31 | + measurements (collected by the EFW experiment), and spacecraft electrons can be | ||
| 32 | + properly removed. The current release has been generated automatically | ||
| 33 | + using default values to control the approach to | ||
| 34 | + potential correction and photoelectron removal, and has not been systematically human | ||
| 35 | + - validated, so some errors may exist. | ||
| 36 | + Specifically, the spacecraft potential, Vsc, is set to be 1 V greater than the | ||
| 37 | + measured probe - spacecraft potential provided by | ||
| 38 | + the electric field experiment (EFW) and the lower energy cutoff for the moments | ||
| 39 | + integration is set to reject the energy bin | ||
| 40 | + containing the EFW potential and the one above that (which in practice | ||
| 41 | + may also contain counts due to spacecraft electrons). | ||
| 42 | + Sometimes cold electrons are present which can appear in the same energy bin as the spacecraft photoelectrons, | ||
| 43 | + therefore both the cold electrons and spacecraft photoelectrons are removed resulting in underestimated electron densities. | ||
| 44 | + Recent work | ||
| 45 | + by the EFW team suggests a more accurate determination of from would be a term that increases linearly | ||
| 46 | + above ~10 V (Cully et al., 2007) but this has not yet been | ||
| 47 | + implemented in our CAA moments generation code.</Description> | ||

| 10 | - <Description>The primary task of this instrument (PEACE: Plasma Electrons and Currents Experiment) | ||
| 11 | - is to obtain the velocity moments of the distribution function of electrons as frequently and | ||
| 12 | - as accurately as the spacecraft telemetry will allow. Detector counts are collected in energy, | ||
| 13 | - polar-angle, and azimuth-angle bins to form a three-dimensional matrix. | ||
| 14 | - Two sensors are used: LEEA (low-energy electron analyzer) and HEEA (high-energy electron analyzer). | ||
| 15 | - The energy coverage is from 0.67 eV to 30 KeV in 92 levels. The first 16 levels are equally spaced linearly | ||
| 16 | - up to 10.7 eV; the remainder are logarithmically spaced. Both sensors can use the full range, but the HEEA | ||
| 17 | - will normally operate over a higher energy range than the LEEA. The LEEA specializes in coverage of the | ||
| 18 | - energies from 0.7-10 eV, and has a geometric factor one fifth that of the HEAA. Both sensors consist of | ||
| 19 | - hemispherical electrostatic analyzers of the top-hat type and a detector in the form of an annular | ||
| 20 | - micro-channel plate with a position-sensitive readout. Each sensor covers the range 0-180 degrees | ||
| 21 | - with respect to the spin axis, and they are mounted opposite each other with a view perpendicular | ||
| 22 | - to the spin axis, thus covering the complete angular range in a half rotation of the spacecraft. | ||
| 23 | - The field of view perpendicular to the fan is 2 degrees for the LEEA and 5.6 degrees for the HEEA. | ||
| 24 | - Energy resolution (Delta-E)/E is 0.13 for LEEA and 0.16 for HEEA. There are four sweep modes, | ||
| 25 | - synchronized to the spin period (4 s), to vary the azimuthal angular resolution. | ||
| 26 | - The spin phasing can be made coincident with that of the CIS instrument, to ensure that the electron | ||
| 27 | - and ion moments will be measured simultaneously. On-board processing is used to calculate the moments | ||
| 28 | - of the distribution with an accuracy of 1% and to select suitable parts of the complete distribution | ||
| 29 | - for transmission. The normal science data format is based on one spin period, and consists of core data | ||
| 30 | - followed by other optional distributions as can be fit into the available telemetry for that spin. | ||
| 31 | - The core data (moments, spacecraft potential, and pitch angle distribution) are always transmitted | ||
| 32 | - (if the spin is nominal). The next distribution is transmitted if, before the end of the spin, | ||
| 33 | - all the previous data have been sent. Thus the next spin of data will be transmitted slightly late, | ||
| 34 | - but all of its core data will be transmitted before the following spin of data is started on. | ||
| 35 | - Eventually the transmission will catch up and be able to transmit the distribution after the core again, | ||
| 36 | - but only after some time. This applies at all telemetry rates. The instrument can adapt automatically to | ||
| 37 | - six different telemetry rates: a basic 1.52 Kbps rate (CIS priority); a normal 2.52 Kbps rate; | ||
| 38 | - an enhanced PEACE priority rate of 3.54 Kbps; and three burst mode rates, with a maximum of 15.98 Kbps. | ||
| 39 | - For more details of the Cluster mission, the spacecraft, and its instruments, | ||
| 40 | - see the report Cluster: mission, payload and supporting activities, March 1993, ESA SP-1159, | ||
| 41 | - and the included article PEACE: a Plasma Electron and Current Experiment, by A. D. Johnstone et al., | ||
| 42 | - from which this information was obtained.</Description> | ||

| 10 | + <Description> The CAA Moments data are electron density, velocity vector, | ||
| 11 | + pressure tensor and heat flux vector. The vectors and tensors are provided in GSE coordinates. Velocity and temperature | ||
| 12 | + are also provided as components perpendicular and parallel to the magnetic field. | ||
| 13 | + The magnetic field data is taken from CSDS FGM PP data, at present. In a possible future | ||
| 14 | + release we would ideally use CAA FGM data, but it is considered unlikely that there will be major differences except in | ||
| 15 | + very weak field regions. Furthermore : | ||
| 16 | + * T_perp and T_para are determined by projecting the pressure tensor along the magnetic field and dividing by the density and by Boltzmanns constant. T_perp is the average of the two perpendicular components. | ||
| 17 | + * v_para = (v.b) b and v_perp = v - (v.b) b. where v is the velocity vector and b is the magnetic field unit vector. | ||
| 18 | + | ||
| 19 | + These data are produced on the ground using 3-D data and thus are available at time resolutions which are limited by the | ||
| 20 | + rate at which 3-D data can be transmitted. The data source used to generate the mome | ||
| 21 | + nts is always the best available resolution 3-D data; this means mainly 3DR data but in the case 3DX or 3DXP are available these | ||
| 22 | + are used instead for the MOMENTS production (see Mode_DataOrigin_HEEA/LEEA). Choices on the best way to combine data from the two | ||
| 23 | + sensors can be made in the moments production software; in the first release the moments are made using LEEA data in the | ||
| 24 | + energy overlap region. | ||
| 25 | + In some situations, use of both sensors together may be a better choice, for example in case | ||
| 26 | + s where the distribution changes | ||
| 27 | + during a spin as the method can resolve time aliasing errors. If resources allow, the Moments | ||
| 28 | + product at CAA may be updated to take advantage of this possibility. | ||
| 29 | + The advantage of these ground - calculated moments is that the best available | ||
| 30 | + calibration data is used, a correction can be made for the spacecraft potential | ||
| 31 | + measurements (collected by the EFW experiment), and spacecraft electrons can be | ||
| 32 | + properly removed. The current release has been generated automatically | ||
| 33 | + using default values to control the approach to | ||
| 34 | + potential correction and photoelectron removal, and has not been systematically human | ||
| 35 | + - validated, so some errors may exist. | ||
| 36 | + Specifically, the spacecraft potential, Vsc, is set to be 1 V greater than the | ||
| 37 | + measured probe - spacecraft potential provided by | ||
| 38 | + the electric field experiment (EFW) and the lower energy cutoff for the moments | ||
| 39 | + integration is set to reject the energy bin | ||
| 40 | + containing the EFW potential and the one above that (which in practice | ||
| 41 | + may also contain counts due to spacecraft electrons). | ||
| 42 | + Sometimes cold electrons are present which can appear in the same energy bin as the spacecraft photoelectrons, | ||
| 43 | + therefore both the cold electrons and spacecraft photoelectrons are removed resulting in underestimated electron densities. | ||
| 44 | + Recent work | ||
| 45 | + by the EFW team suggests a more accurate determination of from would be a term that increases linearly | ||
| 46 | + above ~10 V (Cully et al., 2007) but this has not yet been | ||
| 47 | + implemented in our CAA moments generation code.</Description> | ||
