MEX-M-ASPERA3-2-EDR-NPI

Overview: The Neutral Particle Imager (NPI) measures integral ENA fluxes in the energy range 0.1 to 60 keV to help satisfy the following scientific objectives: 1. Determine the instantaneous global distributions of plasma and neutral gas near Mars 2. Energy deposition from the solar wind to the ionosphere 3. Search for the solar windPhobos interactions Parameters: All NPI data products have the same format and parameters, and each row (data file record) in the NPI SPREADSHEET data products has eight (8) COLUMN objects (parameters): 1. Start Time Begin Date/Time in UTC of data samples 2. Stop Time Ending Date/Time in UTC of data samples 3. Data Type Name either SENSOR or MODE. The SENSOR rows are the NPI science data for each sector (32 sectors). The MODE rows contains informational data like Accumulation Time and MCP Mode. 4. Data Type Id Numeric ID indicating either SENSOR or MODE. 5. Data Name Short description for data on that row. For example Sector 0 for NPI sector 0 science data (SENSOR row), or Accumulation Time for informational data (MODE row). 6. Data Unit Indicates the data unit (c/acc for SENSOR data, unitless for MODE data). 7. Values These are the actual data values. For NPI, there is one value per row (sector). 8. Data Quality Value Quality indicator for the data on that row. See CONFIDENCE_LEVEL_NOTE under Data Coverage/Quality for valid values and descriptions. Data Products: The only Standard Data Product for NPI PSA Level 1b (EDR) is: 1. NPINORM_C_ACC Neutral Particle Imager NORMal mode data in Counts / ACCumulation units. Ancillary Data: It is important for ASPERA3 science studies to know where in space and time the Mars Express spacecraft and ASPERA3 instruments are located and what objects (Sun, Mars, Earth, Phobos, Deimos) are in the fields of views. The ASPERA3 view directions for each sensor can be derived using the SP truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
