Energetic electron count rates and fluxes measured by the EPD instrument
onboard Galileo in the Record acquisition mode. 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].
