Karen,

Thanks for the analysis.  It sounds like either AIJ or ASTAP is handling this incorrectly.  I have posted a link to your response in the ASTAP forums to see what the developer thinks.

I've seen many places that Canon uses RGGB.  However, there could be an ambiguity in how you enumerate things.

Is RGGB this:

RG
GB

or

RG
BG

where in the second case you order starting from top left and proceeding in a clockwise direction.
