What is currently called "Point_source_resonse.ipynb" will change names to "SpacecraftFile.ipynb" and focus on the coordinates, orientation, etc. (described in 2. above)
I'll add the explanation of the scatt map to SpacecraftFile.ipynb
@Yong2Sheng will move the actual point source calculation to “DetectorResponse.ipynb” (that is, replacing my code with a fake orientation history)
