Test F3C - Quality of Observing Condition

Goal: SPC is highly dependent on the stereo angle and illumination conditions of the images. However, there has not been a systematic study to show how much those parameters affect the accuracy of the solution. We will test the accuracy by adding a few images with better stereo and photoclinometry angles.

This has been supported by Test 09 OrbitBUltra, Test 10 UltraFeatureF2 and T11 ReferencePeaks, tests conducted as part of the Calibration Test Phase.

Relative Accuracy

Sub-Test F3C-1 - Matched Pairs

Four images with observing conditions matched with the Sun position. Meets MRD-576.

Sub-Test F3C-2 - Cross Pairs

Four images with observing conditions different for each pair of images. Meets MRD-576.

Sub-Test F3C-3 – Matched Pairs

Three images, all on the same side and with only 10° difference in position. Meets MRD-576.

Sub-Test F3C-4 – Crossed Pairs

Three images, on opposite sides and with only 10° difference in position. Meets MRD-576.

Sub-Test F3C-5

Every 45° with minimum Sun angle change. Meets MRD-576

Sub-Test F3C-6

Every 45° with opposite sides for Sun position. Meets MRD-576
