"Was this done to correct for the vidicon distortion or to make it possible to mosaic them without getting ugly seams?"
Vikings vidicons had relatively small geometric distortion (compared to previous Martian mission Mariner 9). So I did warping only for mosaicking and resizing (bUnwarpJ does both things in one process). Only problems are with corners, which have most severe geometric distortion. So if possible, I used central parts from overlapping images, which have lowest geometric distortion. "Spacecraft motion between frames?" It looks, that spacecraft motion between frames was relatively low. After all, Viking was in higher (and slower) part of his orbit. -------------------- |
