SYNOPSIS

esorex naco_img_twflat [OPTIONS] FILE.sof

DESCRIPTION

naco_img_twflat -- NACO imaging flat-field creation from twilight images.

The files listed in the Set Of Frames (sof-file) must be tagged: raw-file.fits CAL_FLAT_TW or raw-or-calib-file.fits CAL_DARK The flat frames are divided into groups, each group having identical instrument settings. Each group of flats is reduced independently of each other. For each group of flats, the set of frames shall contain either zero, one or n dark frames with the same instrument settings, where n is the number of flats in the group.
