= 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. Data: Nominal Orbital B and extra images (Use OBOptimal w/ Error orbital the Requirements) Start: 35cm Detailed Survey Shape model Build: TAG Site #1 Use the "quality diagrams" to see where to add images Supports Safety map, FDS and NFT Sub-Test F3C Include non-physical solar angles to show the improvement of photoclinometry Evaluate: Accuracy Relative Accuracy Sub-Test F3C-1 - Matched Pairs.
