data_science_calibrated 1098 PDS DSV 1 Calibrated Science Data from NSS aboard Astrobotic Peregrine Mission-1 Lander 6986 Carriage-Return Line-Feed Comma 10 2 datetime 1 ASCII_Date_Time_YMD UTC Date time when record was collected, YYYY-MM-DDTHH:mm:ss.fffZ format, example : 2024-01-08T14:02:31.595Z Det1_PHA_channels 1 32 1 0 Number of events recorded per spectral channel. Note: this field is repeated 32 times, one for each of 32 channels corresponding to deposited energy in Detector 1. “chXX” refers to each channel, starting from 0. Det1_PHA_channels ASCII_String counts/bin Det2_PHA_channels 2 32 1 0 Number of events recorded per spectral channel. Note: this field is repeated 32 times, one for each of 32 channels corresponding to deposited energy in Detector 2. “chXX” refers to each channel, starting from 0. Det2_PHA_channels ASCII_String counts/bin Det1_ScalarCounts 2 ASCII_Integer Number of events crossing a commanded threshold discriminator level. Det2_ScalarCounts 3 ASCII_Integer Number of events crossing a commanded threshold discriminator level. Det1_Threshold 4 ASCII_Integer keV Discriminator threshold for Detector 1 events. Example: a pulse that is equivalent to 60 keV energy deposition will not be counted if the threshold is set to 94 keV. An entry of “disable” means the pulse height spectrum is disabled during this measurement. Det2_Threshold 5 ASCII_Integer keV Discriminator threshold for Detector 2 events. Example: a pulse that is equivalent to 60 keV energy deposition will not be counted if the threshold is set to 94 keV. An entry of “disable” means the pulse height spectrum is disabled during this measurement. High_Voltage_Setting 6 ASCII_Real V Commanded high voltage setting. High_Voltage_Value 7 ASCII_Integer V Actual high voltage value. Sensor_Module_Board_Temperature 8 ASCII_Real degC Value from NSS thermistor lookup table, thermistor_table.csv. Data_Processing_Module_Board_Temperature 9 ASCII_Real degC Value from NSS thermistor lookup table, thermistor_table.csv. quality_flag 10 ASCII_String Number indicating any off-nominal conditions during the measurement. If present, multiple values will be encoded as a comma-separated list. Possible values are: 0: Sensor module powered off 1: Nominal operations 2: Watchdog reset toggle at 1 3: Off nominal SM temperature (outside of AFT) 4: Off nominal DPM temperature (outside of AFT) 5: Off nominal high voltage (+/- 20 V) 6: Off nominal component voltage (+/- 1 V) 7: Solar particle event 8: Missing data packets 9: Commanded parameter change causes high voltage change Any data with a value other than 1 should be treated with caution when used for scientific interpretation.
