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,

  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.

  46 + above ~10 V (Cully et al., 2007) but this has not yet been

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>
