                This data set contains Calibrated data taken by the                     
                New Horizons Pluto Energetic Particle Spectrometer Science Investigation
                (PEPSSI) instrument during the PLUTO ENCOUNTER mission phase. These data 
                were migrated from the PDS3 dataset: NH-P-PEPSSI-3-PLUTO-V3.0.
                 
                During the Pluto Charon Encounter mission phase starting in             
                January, 2015, there were several sub-phases: three Approach            
                sub-phases, (AP1, AP2 and AP3); a CORE sequence for the Pluto           
                flyby on 14 July, 2015 (Day Of Year 195), sometimes also referred       
                to as NEP (Near-Encounter Phase); three Departure sub-phases            
                (DP1, DP2, DP3); a Transition sub-phase ending in late October, 2016,   
                closing out the Pluto Encounter mission phase.  For this final PEPSSI   
                delivery for the Pluto mission phase, this data set includes the        
                Approach data plus the CORE and Departure sequences' data, as well as   
                normal operation and Calibration Campaign data during Transition, and   
                has all data downlinked through the end of October, 2016.               
                
                Due to a spacecraft safing event on 04 July, 2015 (DOY 185), the        
                balance of the science load from then-executing 15184 sequence          
                (nominal start time on DOY 184 in 2015) was sacrificed to ensure the    
                15188 CORE load with the flyby sequence could be loaded onto the        
                spacecraft and started on time.  As a result, there is a gap in the     
                PEPSSI data from approximately DOY 186 to DOY 188.      
                
                Labels were redesigned during migration using the .FIT header and PDS3 .LBL
                files, but the data files are unchanged from their PDS3 version.
