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.
