Switch default reference catalog for DECam to PS1 in LSST format

    Details

      Description

      Following obs_subaru, it would be nice to change the configuration files of obs_decam so to also use the PS1 catalog in LSST format and remove dependence on astrometry.net.

            As you reviewed DM-9438, would you mind reviewing this ticket for the same changes in processing DECam?

            Besides obs_decam, I also needed to change the config file in validate_drp for it to continue using astrometry_net, following the lead of DM-9909.

            Jenkins including lsst_ci passed with one p3 still running.

            Hsin-Fang Chiang Alternatively, you could provide a PS1-style catalog for the data in validation_data_decam. Is this something that would be relatively straightforward to do?

            I'd rather CI the way we generally use the packages.

            Beyond Michael Wood-Vasey and Paul Price's comments re: not using a.net and remapping u->g for photometry, I don't see any other recommended changes.

            Thanks for the review.

            re: filter map, as I don't have the color term, I've added a comment to warn the users.

            re: a.net usage in validate_drp, I'm not sure if this is straightforward and I'm not familiar with the data in validation_data_decam, but I've created two new tickets: DM-11648 for decam and DM-11647 for hsc so they don't get forgotten.

            Now one can processCcd decam data without worrying about astrometry.net. For example on lsst-dev one can do:

            processCcd.py /datasets/decam/ --id visit=177344 ccdnum=3 --calib /datasets/decam/_internal/calib/cp201302/ -C $OBS_DECAM_DIR/config/processCcdCpIsr.py  --rerun private/username/ 
            

            The above was tested with w_2017_33 + new obs_decam.
