bad pixel correction on MEF images

Rach wrote on Jan 19, 2007

How can I correct bad pixels in an MEF using a mask which is also an MEF? The mask has 36 extensions, each corresponds to an extension in the main image I want to process. Is it possible to interpolate bad pixels without splitting the MEF and running fixpix 36 times?

Frank can comment further, but I think the MSCRED package task MSCCMD can do this as a way to e.g. run FIXPIX on each on the image extensions where the corresponding mask extension is used for the correction. Something like

cl> msccmd "fixpix $input $in2" mefs.fits masks.fits out.fits

Otherwise, the FITSUTIL package is handy for dealing with MEFs.

Cheers,
