dear all ive got a whole bunch of images which can have a significant shift in x,y between frames. i've put them through findobj/findoff/register/tranndf in ccdpack, so images now have both the original XY plus a common XY embedded in the frames - i believe put into a domain called CCD_REG. however, when i put the images into autophotom, it still picks up the original XY not the common XY in CCD_REG. how can i get it to pick up the common XY co-ords? many thanks gav ------------------------------------------------------------------------------- Gavin Ramsay E-mail: [log in to unmask] Armagh Observatory College Hill Phone (direct) : (+44) 028 3751 2951 Armagh BT61 9DG http://www.arm.ac.uk/~gar Northern Ireland ------------------------------------------------------------------------------- ---- Starlink User Support list For list configuration, including subscribing to and unsubscribing from the list, see https://www.jiscmail.ac.uk/cgi-bin/webadmin?A0=STARLINK
