HP3 geometric calibration data of the far spot sensors signal as function of azimuth clockwise relative to the nominal north direction.

This table provides the signal (thermopile voltage) measured by the HP3 radiometer when observing a collimated infrared beam at various angles horizontally across the center of field of view (FoV) 2. The nominal boresight of FoV 2 is at -25° elevation relative to the lander deck, and -20° clockwise azimuth from nominal north. The observation angle is transformed from the laboratory reference frame to azimuth relative to nominal north. The signal is corrected for background drift by chopping the infrared source.
