I got to wondering if the elevation and aziumth values in the JPG metadata reflected the misalignment of the filters -- and they apparently do!

The A, B , C filters in this image have elevation and azimuth values:

• -18.161, 122.59


• -18.1591,122.588


• -18.1587,122.589

SO, the SSI camera seems to know where it is pointed to 7 decimal places when the exposure is taken -- and so either it is commanded to misalign the filters -- or the command sequence is first point to some specific value ( like, say -18.16, 122.59 ) and then take a sequence of exposures, noting the actual pointing -- or perhaps the actual pointing is calculated from the images once they are downlinked???

So I wonder which it is: obfiscation or lander movement -- or some other effect? All of the above???

As an aside, the local times for the A, B, C exposures were 18:43:59, 18:44:49, 18:45:41 with exposures of 1.0455, 1.1628 and 3.0957 seconds.

I wonder what factors control the time between filter exposures? Is 50 seconds a minimum?

Lots of questions. Damn few answers.
