The images are not overscan subtracted nor trimmed since there is no standard trimsec or biassec
Multi-extension FITS image converted into a single FITS image via inemmi.prg
Very few defects in the EMMI-RED mosaic
The edge of the FOV (seen in the FLATHIGH.fits) is detected by
mkBADPIX.pl This is not important though, since this area will have to
be trimmed in the reduction process anyway.
Example Comparisons:
Notes:
The strong line down the middle is actually the break between the
different CCDs. Although there are different levels detected in
FLATLOWHIGH.fits, they are not picked up as bad columns.
Notes:
Detects the real bad column on the left hand side
Detects the edge of the FOV and gaps between chips as well.
However, this is not important since the image will have to be trimmed
and the gap between the chips contains no scientific information.
