NAME |
Galileo EPD Calibrated Corrected High 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 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.
