Table B.6 defines the Averaging Step. These data will be used to verify calibration gainand offset coefficients, as needed for all Averaging Modes, can be computed from the 1x1 highresolution data.Table B.6. Averaging Mode StepLine Repeat No.(40.8 msec/ line)An A B C D1 1x1 1x1 4x4 1x1 1x132 1x1 1x1 1x1 4x4 1x165 1x4 1x4 1x4 1x4 1x4129 4x4 4x4 4x4 4x4 4x4Note: Total time = 192 lines * 40.8 msec = 7.83 sec = 0.13 min.Here the cameras are sequenced between data averaging modes. The first four cases in thistable are needed to collect unaveraged data over the poles. Because of the limited peak data rate, Ibelieve only 18 channels can be in 1x1 at any one time (we need 20 channels to collect unaverageddata simultaneously).Table B.7 defines the Local Mode Step. These data are used to verify the instrument responsein Science Local Mode. The instrument output in this Step should be predictable from the 1x1response data.Table B.7.

It will run for 10 cycles (about 1 minute). Itis desirable to not run the goniometer during the entire calibration window, in case motor noisedisturbs the camera and photodiode measurements. The activation of the goniometer is not limitedbecause of the uncompensated momentum requirement. There is some loss of science data,however, due to the uncompensated momentum requirement.In-flight Radiometric Calibration and Characterization Plan, JPL D-1331593
