Dear Bryan,
As Mark van Raaij pointed out you have complete
flexibility in specifying the images to be used in autoindexing or in
cell refinement.
However, the default behaviour is to use the first image and a second
image that is as close as possible to 90 degrees away f
afaik Mosflm will index on whatever spots you have told it to find and not
discard, be they from 1 image, 2, or 10 or more images at any relative angle or
oscillation range. Or it won't successfully index, depending on the difficulty
of the case (several lattices, spot overlap etc...).
Indexing
I seem to have noticed that (i)mosflm can index on one image, or two
images that are not related by 90 degrees. also, cell refinement
sometimes splits up a set of frames into maybe 3 or four segments of
e.g. a few degrees each. and of course, I can set it based on frames
90 degrees apart.
