NAME

       sinfo_rec_mflat - Master flat determination

SYNOPSIS

       esorex sinfo_rec_mflat [OPTIONS] FILE.sof

DESCRIPTION

       This recipe reduce normal raw flat fields.

       The  input files are a set of flat fields with tag FLAT_LAMP optionally
       one may have in input also several bad pixel maps to be coadded.

       The main products are a master flat  field  (PRO.CATG=MASTER_FLAT_LAMP)
       image  a  bad  pixel  map  (PRO.CATG=BP_MAP_NO), a master bad pixel map
       (PRO.CATG=MASTER_BP_MAP) resulting by the coaddition of all  bad  pixel
       maps.
