In this mode, the count rates are accumulated during around 1.25 second. The full opening angle of the EPD telescopes are relatively narrow, between 15° and 18°, and the acquisition period is very short compared to the rotational spin period of Galileo. Counts and fluxes obtained with the Record acquisition mode can therefore be considered as directional flux measurements. The local and equatorial pitch angles that are given are for the particles observed by the center of the telescope viewing cones. The motor that rotates the EPD telescopes around an axis perpendicular to the spin axis of Galileo can have eight different step positions, from 0 to 7. Data are extracted from the text file named 'galileo_epd_calibrated_low_res_v18.txt' produced and provided by JHU/APL and publicly available at http://sd-www.jhuapl.edu/Galileo_EPD/latest_calibrated_data/. It is highly recommended to read the "readme_v19.docx" document also available at the previous link before using this dataset. It is also recommended to contact Peter Kollmann (JHU/APL), as some measurement channels are highly contaminated or saturated. All unreliable measurements are set to NaN. Energies, species and charge states observed by each measurement channel are discussed in detail in Kollmann et al. [2018, JGR]. * 1996-09-06T18:32:45 1996-09-06T19:28:22 * 1997-04-05T06:44:41 1997-04-05T07:40:18 * 1997-05-07T15:36:54 1997-05-07T16:22:23 * 1997-12-15T09:30:24 1997-12-15T10:30:00 * 2000-05-20T09:40:04 2000-05-20T10:40:41 * 2000-12-28T07:54:42 2000-12-28T08:55:20 spase://SMWG/Person/Donald.J.Williams PrincipalInvestigator spase://CNES/Person/Peter.Kollmann DataProducer spase://CNES/Person/Quentin.Nenon DataProducer spase://CNES/Person/Christopher.Paranicas CoInvestigator spase://CNES/Person/Norbert.Krupp CoInvestigator Access to data at JHU/APL http://sd-www.jhuapl.edu/Galileo_EPD/latest_calibrated_data/ gll-epd-record-ion PartOf record mode : ion channels spase://SMWG/Repository/CDPP/AMDA http://amda.cdpp.eu NetCDF JHU/APL http://sd-www.jhuapl.edu/Galileo_EPD/latest_calibrated_data/galileo_epd_calibrated_low_res_v18.txt spase://CNES/Instrument/CDPP-AMDA/Galileo/EPD EnergeticParticles 1996-05-27T00:14:24Z 2003-09-21T18:15:57Z PT600S PT720S Jupiter Ion Channels : * A[0-7] : M ≥ 1, Charge ≥ 1; 22 - 3200 keV * A8 : M ≥ 4, Charge ≥ 2; 3480 - 8200 keV * B0 : H+ ; 3500 -10000 keV * B2 : M ≥ 4, Charge ≥ 1; 16 -100 MeV (counts only) * TP[1-3] : H+, 80 - 1140 keV * TA[1-2] : He, Charge all; 108 - 4000 keV * TO[1-4] : O, Charge all; 192 - 8992 keV (TO1 counts only) * TS[1-3] : S, Charge all; 512 - 9920 keV * CA[1,3,4] : He, Charge all; 76 - 5600 keV * CM[1,3,4] : O, Charge all; 2.56 - 171.2 MeV * CH[3-5] : S, Charge all; 12.32 - 840 MeV * CN[0-1] : M ~ 23, Charge all; 23 - 269.1 MeV L-shell gll_epd_l_gaion TimeSeries Other local pitch angle gll_epd_paloc_gaion degree TimeSeries Other motor position gll_epd_motor_gaion TimeSeries Other all : A[0-8] : cnts gll_epd_ga_acnts s**-1 Spectrogram 9 Ion CountRate all : A[0-8] : flux gll_epd_ga_aflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 9 Ion NumberFlux h : B[0,2] : cnts gll_epd_gaion_bcnts s**-1 Spectrogram 2 Proton CountRate h : B[0,2] : flux gll_epd_gaion_bflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 2 Proton NumberFlux h : TP[1-3] : cnts gll_epd_ga_tpcnts s**-1 Spectrogram 3 Proton CountRate h : TP[1-3] : flux gll_epd_ga_tpflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 3 Proton NumberFlux he : TA[1-2] : cnts gll_epd_ga_tacnts s**-1 Spectrogram 2 Ion CountRate he : TA[1-2] : flux gll_epd_ga_taflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 2 Ion NumberFlux o : TO[1-4] : cnts gll_epd_ga_tocnts s**-1 Spectrogram 4 Ion CountRate o : TO[1-4] : flux gll_epd_ga_toflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 4 Ion NumberFlux s : TS[1-3] : cnts gll_epd_ga_tscnts s**-1 Spectrogram 3 Ion CountRate s : TS[1-3] : flux gll_epd_ga_tsflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 3 Ion NumberFlux he: CA[1,3,4] : cnts gll_epd_ga_cacnts s**-1 Spectrogram 3 Ion CountRate he : CA[1,3,4] : flux gll_epd_ga_caflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 3 Ion NumberFlux o: CM[1,3,4] : cnts gll_epd_ga_cmcnts s**-1 Spectrogram 4 Ion CountRate o : CM[1,3,4] : flux gll_epd_ga_cmflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 4 Ion NumberFlux ions: CN[0-1] : cnts gll_epd_ga_cncnts s**-1 Spectrogram 2 Ion CountRate ions : CN[0-1] : flux gll_epd_ga_cnflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 2 Ion NumberFlux s: CH[3-5]: cnts gll_epd_ga_chcnts s**-1 Spectrogram 4 Ion CountRate s : CH[3-5] : flux gll_epd_ga_chflux cm**-2.s**-1.sr**-1.keV**-1 Spectrogram 4 Ion NumberFlux
