MEX-M-ASPERA3-3-RDR-ELS-EXT3

Overview: The Electron Spectrometer (ELS) provides in situ electron measurements in the energy range 0.05 eV to 20 keV to help satisfy the following scientific objectives: 1. Determine the instantaneous global distributions of plasma and neutral gas near Mars by providing undisturbed solar wind parameters 2. Define the local characteristics of the main plasma regions 3. Complement the ENA images Parameters: All ELS data products have the same format and parameters, and each row (data file record) in the ELS 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 SENSOR, SCAN, or MODE. The SENSOR rows are the ELS science data for each sector (16 sectors). The SCAN rows are the deflection voltages (volts) that correspond to the SENSOR rows. There is one SCAN row per 16 SENSOR rows. The 16 SENSOR rows are followed by one corresponding SCAN row. The SCAN row indicates the deflection voltage per step that corresponds to the previous 16 SENSOR rows for each step. To convert the deflection voltages to center energies (eV), use the K_FACTOR per anode in the calibration tables: eV volt * K_FACTOR. There are 16 SENSOR rows + 1 SCAN row (17 in all) followed by 23 rows of MODE data for the same time period. The MODE rows contain informational data such as Time/Step Summations and Sector Enable Flags. 4. Data Type Id Numeric ID indicating SENSOR, SCAN, or MODE. 5. Data Name Short description for data on that row. For example ELS Sector 0 LR for ELS sector 0 Low Range science data (SENSOR rows for ELSSCIL data products), ELS Sector 0 HR for ELS sector 0 High Range science data (SENSOR rows for ELSSCIH data products), Deflection Potential for SCAN rows, or Time Summation for informational data (MODE row). 6. Data Unit Indicates the data unit: cnts/(cm**2srsec truncated!, Please see actual [truncated!, Please see actual data for full text]
