Documentation for this can be found at: $ https://confluence.lsstcorp.org/display/LSWUG/Process+DECam+Images Currently, there is only support for "instcal" (plus dqmask and wtmap) processing.

  1. Create a data repository directory:

     $ mkdir /path/to/repo
 $ echo lsst.obs.decam.DecamInstcalMapper > /path/to/repo/_mapper

  2. Get and build obs_decam:

     $ cd /path/to/work
 $ git clone git://github.com/LSST-nonproject/obs_decam.git
 $ cd obs_decam
 $ setup -t <CURRENT_TAG> -r .
 $ scons install declare --tag=current

  3. Import data into the data repository:

     $ cd /path/to/data
 $ setup -t <CURRENT_TAG> pipe_tasks
 $ setup -k -t <CURRENT_TAG> obs_decam
 $ ingestImagesDecam.py /path/to/repo --mode=link instcal/*.fits

  4. Process data

     $ setup -t <CURRENT_TAG> pipe_tasks
 $ setup -k -t <CURRENT_TAG> obs_decam
 $ processCcdDecam.py /path/to/repo --id visit=283453 ccdnum=10 --config calibrate.doPhotoCal=False calibrate.doAstrometry=False calibrate.measurePsf.starSelector.name="secondMoment" doWriteCalibrateMatches=False --clobber-config
