            Contains derived daily pitch angle spectrogram data for the EPS odd-numbered shaped channels (ion=1,5,7,9). A given pitch angle spectrogram DDR data file contains all the observations obtained on one electron event. The particle measurement is 120 seconds averaged.

                The data in this collection were originally released in 2015 as part of the PDS3 
                MESS-E_V_H_SW-EPPS-3-EPS-DDR-V1.0
                dataset. The metadata have been migrated to PDS4. The data themselves are unchanged.
