NAME

   vmimflatscreen  -  Create  a  master  screen flat field from set of raw
   screen flat field frames.

SYNOPSIS

   esorex vmimflatscreen [OPTIONS] FILE.sof

DESCRIPTION

   This recipe is used to create a master screen flat field from a set  of
   raw  screen  flat  fields.  The  master  screen  flat field is not used
   directly in the flat field correction of scientific  data,  but  it  is
   optionally  used just in the creation of a master sky flat field by the
   recipe vmimflatsky.

   Input files:

     DO category:              Type:       Explanation:         Required:
     IMG_SCREEN_FLAT           Raw         Screen flat exposure    Y
     MASTER_BIAS               Calib       Master bias             Y
     MASTER_DARK               Calib       Master dark             .

     CCD_TABLE                 Calib       Bad pixel table         .

   Output files:

     DO category:              Data type:  Explanation:
     IMG_MASTER_SCREEN_FLAT    FITS image  Master screen flat field
     IMG_COMBINED_SCREEN_FLAT  FITS image  Combined screen flat field

   The primary product is the normalised master screen flat field.

   A secondary product is the combined screen  flat  field,  that  is  the
   result  of  the combination of all inputs but without any normalisation
   applied, and is just used for data quality control. A CCD table must be
   specified in input only if a bad pixel cleaning is requested.

   For more details, please refer to the VIMOS Pipeline Users Guide.
