NAME Galileo EPD Calibrated Corrected Low Res Data Collection
TYPE Data
DESCRIPTION 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 low 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 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.
