This recipe is used to apply basic reduction steps to one exposure made in direct imaging mode. SExtractor v2.1.6 is run on the reduced image, producing a table of detected objects with their instrumental magnitudes, their celestial and image coordinates, and their stellarity index. The image WCS, together with the component describing the instrument optical distortions, is converted into the convention followed by VMMPS (the VIMOS mask preparation software). This set of coefficients, the CO-matrix used in the SAO WCSTools package, is written to the header of the reduced image.

Input files:

  DO category:              Type:       Explanation:         Required:
  IMG_SCIENCE               Raw         Science exposure        Y
  MASTER_BIAS               Calib       Master bias             Y
  MASTER_DARK               Calib       Master dark             .

  IMG_MASTER_SKY_FLAT       Calib       Master sky flat         Y
  PHOT_COEFF_TABLE          Calib       Photometric table       .

  CCD_TABLE                 Calib       Bad pixel table         .

Output files:

  DO category:              Data type:  Explanation:
  IMG_SCIENCE_REDUCED       FITS image  Reduced scientific exposure
  IMG_GALAXY_TABLE          FITS table  List of detected objects

If a photometric table is specified, the magnitude zeropoint, the atmospheric extinction coefficient, and the colour term are copied from the photometric table to the header of the reduced image. A CCD table must be specified in input only if a bad pixel cleaning is requested. The galaxy table is the output of SExtractor converted into FITS format. The content of this table is defined within the VIMOS pipeline DRS, with the only intent of serving the purpose of the involved pipeline recipes. For a customised output SExtractor table, it is always possible to run SExtractor separately, after configuring the native SExtractor parameter files. For a complete explanation of the output parameters please refer to the SExtractor documentation - see for instance:

   http://terapix.iap.fr/rubrique.php?id_rubrique=91/index.html).
