We'll run the new 'fobj*p.fits' images through mscimage with the same
parameters as used before and get 'fmim*p.fits' and 'fmim*.pl' single images and
masks. There are now two versions of mscimaged data:
a) obj*p.fits + mim*p.fits
b) fobj*p.fits + fmim*p.fits; only keeping the fmim*p.fits (can always regenerate
the fobj* using the obj*)
