Data Sets and Information
• instrument host: GALILEO ORBITER
  Information about the GALILEO ORBITER instrument host
• collection: Galileo EPD Calibrated Corrected High Res Data Collection
  These are reprocessed measurements by the Engergetic Particle Detector (EPD) instrument onboard the Galileo spacecraft that orbited Jupiter and measured intensities of ion and electron radiation in the keV and MeV energy range. This set is version 31 of reprocessing and version 1.0 of PDS delivery. Data in the high resolution files include measurements that are binned into channels responding to certain energy and species ranges. The files are comma separated. Invalid entries will have -1.000000E+38 as an entry. The first 4 lines of each data text file provide information on the channels included here: The first line of each file lists the names of the channels included. The second line lists the center energies of these channels in keV. The third line lists the channels again. The forth line lists the mass of the measured particle in AMU. Zero mass refers to electrons. The forth line in the data text file labels the columns that follow in the file. The columns include times, radiation measurements, spacecraft location, instrument look direction, and some supplementary information. Radiation measurements are provided both as best calibrated and cleaned intensities as well as raw, uncorrected count rates. Columns with channel names followed by a "j" include calibrated differential intensities of the given channel. If the value is negative, it should be ignored and particularly not included in averages. For the difference between -1.000000E+38 and all other negative values, see the User Guide. Columns ending with "f" provide differential intensities based on a combination of various channels. Columns ending with "i" include calibrated integral intensities. Columns with plain channel names describe the raw uncorrected count rate. Columns ending with "bg" are raw count rates measured behind the calibration shield. Each following line will provide the same data but for different times. More information can be found in the User Guide. This file provides data with the highest available time and pitch angle resolution. Only a small set of channels is provided, limiting the energy resolution and coverage. If columns with plain channel names have -1.000000E+38 values, you might find valid values in the lower resolution files.
• bundle: Galileo EPD Calibrated Corrected Data Bundle
  These are reprocessed measurements by the Energetic Particle Detector (EPD) instrument onboard the Galileo spacecraft that orbited Jupiter and measured intensities of ion and electron radiation in the keV and MeV energy range. This set is version 31 of reprocessing and version 1.0 of PDS delivery.
• collection: Galileo EPD Calibrated Corrected Delta Event Data Collection
  These are reprocessed measurements by the Engergetic Particle Detector (EPD) instrument onboard the Galileo spacecraft that orbited Jupiter and measured intensities of ion and electron radiation in the keV and MeV energy range. This set is version 31 of reprocessing and version 1.0 of PDS delivery. The TOFxE and DeltaExE files include event data of ion measurements. Event data are different than the channelized data in the high, medium, and low resolution files. Event data record the full information of a measured particle. Every "event" is the measurement of a time of flight (TOF) within the instrument and energy deposited within a detector (TOFxE file), or two energy values deposited within the two detector layers (DeltaExE file). The deposited energy values are generally different from the energy the particle has in the ambient space. Event data provides measured values in the native resolution of the instrument. Because such high resolution increases data volume, event data cannot be taken continuously and downlinked all the time. Only the provided subset of this data was kept. The files are comma separated. Invalid entries will have values of -1.000000E+38. Times are provided in the format Year.DOYHHMMSSM (first column) and fractional year (second column) More information can be found in the User Guide. This file includes measurements by the EPD/CMS/DeltaExE instrument. For each counted event, the energy deposited in the two solid state detector layers (Ej_keV and Ek_keV columns) of the instrument are recorded.

This file includes measurements by the EPD/CMS/TOFxE instrument. For each counted event, the energy deposited in the one solid state detector (Energy_keV column) and the time of flight (TOF_ns) within the instrument are recorded.

Each following line will provide the same data but for different times. More information can be found in the User Guide. This includes the full set of channels covering the full energy and species range of EPD. The time and pitch angle resolution is low. Higher resolution is available for some channels that can be found in the medium and high resolution files.
