description
This file contains Lunar Prospector omni-directional low resolution electron flux data for 1998-12-19 provided for 15 energy bins (~40ev - 20keV) collected over 16 spacecraft rotations (~80 sec), sampling 4 pi steradians twice each spin period over a 1 day duration.

description
This product, EL981219.TAB, was originally released as part of the PDS3 LP-L-ER-4-SUMM-OMNIDIRELEFLUX-V1.0 data set. The metadata have been migrated to PDS4. The data themselves are unchanged, with the exception of the error described below. Some TAB files, in this collection, have been altered to account for erroneous data values found in the electron flux energy bins. The original flagged values delivered by the instrument team are denoted as: missing_constant = 9.999E-99 These values have been flagged by the PPI node denoted as: error_constant = -9.99E-99
