C. 2021 This table contains the Pulse Height Analysis (PHA) data collected by the MESSENGER EPS instrument. Additional details are contained in the CDR SIS document. 2021-06-09 1.0 This product, EPSN_P2014281CDR_V3.TAB, was originally released in 2015 as part of the PDS3 MESS-E/V/H/SW-EPPS-3-EPS-CDR-V1.0 data set. The metadata have been migrated to PDS4. The data themselves are unchanged. 2014-10-08T00:00:04.677Z 2014-10-08T23:59:55.679Z Science Calibrated Heliosphere Magnetosphere Particles Ions Energetic Heliosphere Magnetosphere Particles Electrons Energetic MESSENGER Mission urn:nasa:pds:context:investigation:mission.messenger data_to_investigation MESSENGER Host urn:nasa:pds:context:instrument_host:spacecraft.mess is_instrument_host EPPS Energetic Particle Spectrometer Instrument urn:nasa:pds:context:instrument:epps-eps.mess is_instrument Solar Wind Plasma Stream urn:nasa:pds:context:target:plasma_stream.solar_wind data_to_target Mercury Planet urn:nasa:pds:context:target:planet.mercury data_to_target Mercury Orbit Year 4 2/055050402 2/055136793 25 500 Electrons Pulse Height Analysis 10 3 Ions Pulse Height Analysis MESS-E/V/H/SW-EPPS-3-EPS-CDR-V1.0:EPSN_P2014281CDR_V3 data_to_calibrated_source_product 10.17189/1519740 NASA Planetary Data System This is the first version of this product converted to PDS4.
