NAME

       vimos_ima_det_noise - Detector noise for imaging

SYNOPSIS

       esorex vimos_ima_det_noise [OPTIONS] FILE.sof

DESCRIPTION

       vimos_ima_det_noise -- VIMOS recipe to find readnoise and gain.

       Compute the readnoise and gain for the vimos detectors using two bias frames and two flat field frames.

       The program accepts the following files in the SOF:

           Tag                   Description

           BIAS                  A list of raw bias images
           FLAT_TWILIGHT         A list of raw flat images
           MASTER_BPM            Optional master bad pixel mask or
           MASTER_CONF            Optional master confidence map If a master bad pixel mask or confidence map is
       included then thebad pixels will be flagged during the statistical analysis

OPTIONS

       --thresh <float>
              Rejection threshold in sigma above background (float; default: 5.0). The full name of this  option
              for the EsoRex configuration file is vimos.vimos_ima_det_noise.thresh [default = 5.0].

       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.

       Basic documentation about the EsoRex program can be found at the esorex (1) man page.

       It   is   possible   to   call   the   pipelines   from   python   using  the  python-cpl  package.   See
