This data set contains Calibrated data taken by the New Horizons Pluto Energetic Particle Spectrometer Science Investigation instrument during the Pluto encounter mission phase. This is VERSION 3.0 of this data set. This data set contains PEPSSI observations taken during the the Approach (Jan-Jul, 2015), Encounter, Departure, and Transition mission sub-phases, including flyby observations taken on 14 July, 2015, and departure and calibration data through late October, 2016. This data set completes the Pluto mission phase deliveries for PEPSSI. This is version 3.0 of this dataset. Changes since version 2.0 include the addition of data downlinked between the end of January, 2016 and the end of October, 2016, completing the delivery of all data covering the Pluto Encounter and subsequent Calibration Campaign. Also, updates were made to the calibration files, documentation, and catalog files. Significant changes were made to the PEPSSI packet processing and calibration, too extensive to go into here. Data from all previous data sets should be discarded. Refer to the data set documentation for details about processing of PEPSSI data.
