The images are not overscan subtracted nor trimmed since there is no standard trimsec or biassec
Appears to do a better job than EIS
There are some bad columns detected by mkBADPIX.pl that are not
apparent in the FLATHIGH.fits image. These ARE apparent in
FLATLOW.fits and appear to be residuals from the BIAS image. As described on the main page, these bad columns are present in reduced images and must be masked out. Some of these are also detected in the EIS mask.
Example Comparisons:
Notes:
These columns are an example of those that are not seen in
FLATHIGH.fits, but are seen in FLATLOW.fits and appear to be residuals
from the BIAS image.
Notes:
Again, these columns are an example of those that are not seen in
FLATHIGH.fits, but are seen in FLATLOW.fits and appear to be residuals
from the BIAS image. Also seen in the EIS BADPIX mask.
Doesn't pick up the bad pixel clump a little above the centre of the frame
