I think I've identified an issue with debayering.  The dates in the FITs header (DATE-END, DATE-AVG, DATE-OBS) of the debayered images is one fixed value across all images. I've tried it on two sets of images and got the same result. It also looks like some other FITs header parameters are not carrying across correctly like OBJCTAZ and OBJCTALT.  Further, several FITS header parameters are removed in the debayer images - not sure if this is right or wrong.  Should COLORTYP in the debayered images be set to something other than RGGB?
