                This file contains Lunar Prospector low-resolution electron flux measured for 
                2 energy bins. This data contains the energy values for the centers of the bins,      
                and the times at which the bins were changed to have those values.

                    This product, E_BINS.TAB, was originally released as part
                    of the PDS3 LP-L-ER-4-SUMM-OMNIDIRELEFLUX-V1.1 data set. The metadata
                    have been migrated to PDS4. The data themselves are unchanged.

                        which the energy bin values are applicable until changed. The time        
                        format is given in seconds after 00:00:00 UT on Jan 1, 1970. Leapseconds  
                        are not accounted for in this time format. Each day is assumed to have    
                        86400.0 seconds and year have either 365 or 366 days.
