HP3 radiometer geometric calibration data of the near 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) 1. The nominal boresight of FoV 1 is at -55° 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.

本表格呈现了HP3辐射计在视场（FoV）1的中心处沿水平方向以不同角度观测准直红外光束时所测得的信号（热电堆电压）。视场1的标称光轴相对于着陆器舱面的仰角为-55°，且相对于标称北向的顺时针方位角为-20°。观测角度由实验室参考坐标系转换为相对于标称北向的方位角。通过对红外源进行斩波处理，已对该信号完成背景漂移校正。
