NAME

   vmimflatsky  -  Create a master sky flat field from set of raw sky flat
   field frames.

SYNOPSIS

   esorex vmimflatsky [OPTIONS] FILE.sof

DESCRIPTION

   This recipe is used to create a master sky flat field from a set of raw
   sky  flat fields. The master sky flat field is the dataset used for the
   flat field correction of scientific data.

   Input files:

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

     IMG_MASTER_SCREEN_FLAT    Calib       Master screen flat      .

     CCD_TABLE                 Calib       Bad pixel table         .

   Output files:

     DO category:              Data type:  Explanation:
     IMG_MASTER_SKY_FLAT       FITS image  Master sky flat field

   If a master screen flat is specified, the input sky flat exposures  are
   flat-fielded  with  it, and then just used to determine the large scale
   trends of the instrument response; the result is then multiplied by the
   master  screen  flat.  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.
