[[Test Results]]

'''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.

== Test Set Up ==
'''Data:'''  Specific Detailed survey images with perturbed SUMFILES

'''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
