Purpose of test: Test the effects of emission angle on boulder representation

Image suite: 5cm resolution images all centered on boulder. Emission angles go from nadir to 80deg, 4 sun angles for each emission angle (45, 135, 225, 315)

Results: 20deg max and 50deg max emission angle. 

=== See Keynote presentation in SPC-ORex/Test_Info_documents/Test07/ for more details ===

Conclusion: No practical effect on boulder height. RMS is maybe 10% different.
