Mike, is there an explanation for the occasional missing frame seen at the beginning of some of the "wide" (~180º spin) raw images?

Looks to me like our ground data system didn't command quite enough frames to catch the top limb of the planet in the red channel -- maybe it incorrectly assumes there can't be more than 40 frames in a nadir-centered image, which due to roundoff is not quite true. I'll take a look at it.
