Hi,I'm trying to create a bad pixel mask for each panel of a six-chip mosaic image. I run mscarith to divide one flat by another (creating ratio.fits), and then I run ccdmask individually for ratio.fits[1] through ratio.fits[6]. It creates the first five masks with no trouble, but I get an "ERROR: floating point invalid operation" message when I (try to) create the sixth mask. The range of values in the sixth chip is the same as the other five, and as far as I can tell, there are no pixels with values that are not a number (or anything strange like that). Any idea what might cause this?Thank you!
Jennifer
