Note that because the spacecraft antenna was pointed at the Earth during this pass, we are looking way off nadir in these images, which make them deviate from round significantly in non-map-projected form (and look like cashews in the point-perspective form that we use in our processed products.) It would be interesting to know if there's a way to fix this cosmetically without doing a real map projection.

For cosmetic purposes, one could apply something like y' = sin(y) to the drafts (neither using trajectory, nor shape model), with y=0 near the vertical center, and y interpreted as an angle between about -pi/2 and pi/2.

This was faster than I could do my uploads.

Here my reprojections, JPG versions:

I'm curious to know how the two different processing methods affect your workflow. Your original Brian Swift pipeline version looks about the same as this to my eye, the only difference I see are some uncorrected CCD blemishes (and some global brightness variation, this one is brighter near the terminator.)

Look a little closer to see the residual channel alignment issues. Those are hard to resolve without shape model and trajectory.
This would be more evident with a higher resolution.
