What seems to make sense (although it could also be totally wrong) is that the total RA field must need a mosaic panel RA position offset adjustment proportional to (1-cos(dec))/N RA panels (or similar). At DEC=45, and for a 2 panel RA mosaic, this would be a 30% total RA panel field size position adjustment divided by the 2 panels (left panel left, right panel right). The devil's always in the details (e.g. likely need to map camera rotation to N/S, E/W coordinate vectors), so a deeper code eval with a few good sim tests is needed to sort and fix the bug. BigNoel, since you're already good at setting up the test(s), it might be nice to know what the sim says about a 2W x 1H mosaic on Polaris.....


I was just removing myself from the conversation when it went into 'cos' and 'sin' math functions. After reading the Telescopis code and that work around for the DEC I knew I was way outta my league...
