HP3 radiometer calibration data acquired on Mars in response to changes in temperature of the open dust cover/calibration target.

This data was acquired at the InSight landing site on Mars. The radiometer dust cover is opened and stabilized at various temperatures so that the observed signal from the dust cover area still in the FoV can be used for calibration. <br><br>The data file has columns for start and end time of measurements at each calibration point in seconds since the epoch J2000, and number of data vectors averaged. The other columns are <br>UtcXY : thermopile voltage where X indicates FoV and Y indicates sensor numberTrefXY : thermopile temperature where X indicates FoV and Y indicates sensor numberTsh : radiometer sensor head temperatureTct : calibration target temperaturePsh : sensor head heater powerPct: calibration target heater powerTbb: cavity blackbody temperatureTenv: thermal shroud temperature<br>The columns for cavity blackbody and environment temperature are included so that the table format is identical with the ground calibration data. The variable are unknown ('UNK').<br>Raw data can also be found on the Planetary Data System:https://pds-geosciences.wustl.edu/missions/insight/hp3rad.htm
