NAME

       fors_remove_bias - Subtract bias from input frame

SYNOPSIS

       esorex fors_remove_bias [OPTIONS] FILE.sof

DESCRIPTION

       This  recipe  is used to subtract the overscan and master bias(produced by the recipe fors_bias) from one
       raw data frame. The overscan regions, if present, are used to compensate for variations  of  the  overall
       bias  level  between  master  bias  and  input  raw frame. The overscan regions are then trimmed from the
       result.

       The recipe should allow any fors frame.

       Input files:

         DO category:               Type:       Explanation:         Required:
         ANY_CAT
                         Raw         Raw data frame          Y
         MASTER_BIAS                Calib       Master bias frame       Y

       Output files:

         ANY_CAT_UNBIAS             FITS image  Bias subtracted frame

OPTIONS

       Note that it is possible to create a configuration file containing these  options,  along  with  suitable
       default values. Please refer to the details provided by the 'esorex --help' command.
