Data Sets and Information
• collection: MESSENGER EPPS EPS Raw Pulse Height Data Collection
  Uncalibrated Pulse Height Analysis data in binary table format. The PHA EDR format was changed by FSW6 on 8/18/2008.
• collection: MESSENGER EPPS EPS Raw Scan Rates Data Collection
  Contains the integrated hardware counters over four energy thresholds. Each threshold setting and integration lasts 1/4 second. New FSW6 EDR introduced on 8/18/2008.
• collection: MESSENGER EPPS EPS Calibrated Pulse Height Data Collection
  EPS calibrated Pulse Height Analysis data in ASCII table format. The lack of priority groups after the FSW6 load on 8/18/2008 means the weight and group columns of the data are not meaningful after that time.
• collection: MESSENGER EPPS EPS Raw Low Resolution Spectra Data Collection
  EPS low resolution (energy channel) uncalibrated ion and electron energy spectra and rate counters. New FSW6 EDR introduced on 8/18/2008, replaces EPS_MED_SPECTRA.
• collection: MESSENGER EPPS Engineering and Status Information Data Collection
  EPPS engineering and status information. This product was retired with the switch to FSW6, 8/18/2008.
• bundle: MESSENGER EPPS Engineering Raw Data Bundle
  This bundle contains the MESSENGER Energetic Particle and Plasma Spectrometer (EPPS) engineering data and the raw data SIS document. These data are associated with the MESSENGER EPPS EPS Raw Data Bundle, and the MESSENGER EPPS FIPS Raw Data Bundle.
• bundle: MESSENGER EPPS EPS Raw Bundle
  This bundle contains the MESSENGER Energetic Particle and Plasma Spectrometer (EPPS) EPS uncalibrated observations, also known EDR. EPS covers the energy range of 25 to > 500 keV for electrons, and 10 keV/nucleon to ~3 MeV/nucleon for ions. These data were previously released as a PDS3 data set (MESS-E/V/H/SW-EPPS-2-EPS-RAWDATA-V2.0, https://doi.org/10.17189/1519738).
• collection: MESSENGER EPPS EPS Calibrated High Priority Spectra Data Collection
  EPS high energy resolution calibrated spectra similar to the EPS_HIRES_SPECTRA product, but with the configuration from before the new FSW6 load on 8/18/2008.
• collection: MESSENGER EPPS EPS Derived Daily Pitch Angle Spectrograms Data Collection
  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.
• collection: MESSENGER EPPS EPS Derived Pitch Angle Data Collection
  EPS derived pitch angles for each of the six look directions reported at the same cadence as the EPS LoRes Spectral rate measurements. Each file thus has a one-to-one relationship with a corresponding LoRes spectral file.
• collection: MESSENGER EPPS EPS Calibrated Medium Priority Spectra Data Collection
  EPS lower energy resolution calibrated spectra similar to the EPS_LORES_SPECTRA product, but with the configuration from before the new FSW6 load on 8/18/2008.
• collection: MESSENGER EPPS EPS High Priority Housekeeping Data Collection
  EPS high priority housekeeping. This product was retired with the switch to FSW6, 8/18/2008.
• collection: MESSENGER EPPS EPS Raw Summary Spectra Data Collection
  Contains a subset of EPS rate counters and low resolution uncalibrated energy spectra. New FSW6 EDR introduced on 8/18/2008.
• collection: MESSENGER EPPS EPS Calibrate Scan Rate Data Collection
  Integrated EPS hardware counters over four energy thresholds. Each threshold setting and integration lasts 1/4 second. Rates are reported in both raw and 'delta' form, see SIS document for details. CDR available only after FSW6 (8/18/2008).
• collection: MESSENGER EPPS EPS Raw High Priority Spectra Data Collection
  High priority uncalibrated EPS Spectra. This product was retired with the switch to FSW6, 8/18/2008.
• collection: MESSENGER EPPS EPS Calibrated High Resolution Spectra Data Collection
  EPS high resolution (energy channels) calibrated ion and electron energy spectra. Replaces EPS_HI_SPECTRA after FSW6 (loaded on 8/18/2008).
• collection: MESSENGER EPPS EPS Calibrated Low Resolution Spectra Data Collection
  EPS low resolution (energy channel) calibrated ion and electron energy spectra and rate counters. Replaces EPS_MED_SPECTRA after FSW6 (loaded on 8/18/2008).
• collection: MESSENGER EPPS EPS Calibrated Summary Spectra Data Collection
  Contains a subset of EPS rate counters and low resolution calibrated energy spectra. CDR available only after FSW6 (8/18/2008).
• collection: MESSENGER EPPS Engineering and Long Status Information Data Collection
  The engineering and status information for the EPPS instrument. New FSW5 EDR introduced on 9/6/2007.
• collection: MESSENGER EPPS EPS Raw High Resolution Spectra Data Collection
  High resolution (energy channels) uncalibrated ion and electron energy spectra. New FS W6 EDR introduced on 8/18/2008, replaces EPS_HI_SPECTRA.
• collection: MESSENGER EPPS EPS Raw Medium Priority Spectra Data Collection
  Uncalibrated EPS medium priority spectra. This product was retired with the switch to FSW6, 8/18/2008.
