1. Full Command Line ExampleΒΆ

Here we put together several of the tools to show how it can all work, from beginning to end.

  1. First create the lists. One for the darks, one for the flats, and one for the science target.

    $ dataselect ../raw/*.fits --tags DARK --expr='exposure_time==20' -o darks20s.lis
    $ dataselect ../raw/*.fits --tags FLAT -o flats.lis
    $ dataselect ../raw/*.fits --expr='object=="SN2014J"' -o target.lis
    
  2. Set the calibration manager and database. First, create or edit the ~/.geminidr/rsys.cfg to look like this:

    [calibs]
    standalone = True
    database_dir = <path_to>/redux_dir/
    

    Then initialize the calibration database.

    $ caldb init
    
  3. Reduce the darks and add the master dark to the calibration database.

    $ reduce @darks20s.lis
    $ caldb add N20160102S0423_dark.fits
    
  4. Reduce the flats and add the master flat to the calibration database.

    $ reduce @flats.lis
    $ caldb add N20160102S0373_flat.fits
    
  5. Reduce the science target, with some input parameter override.

    $ reduce @target.lis -p skyCorrect:scale=False
