I am trying to understand how the Monster reference catalogue was used for DP2 LSSTCam calibration.
On the DP2 RSP Butler, I find the reference catalogue the_monster_20250219, from the collection:
refcats/DM-49042/the_monster_20250219
When I inspect this catalogue, I see synthetic photometry for systems including ComCam, DES, LATISS, and SDSS, but I do not see any monster_LSSTCam_* or SynthLSST flux columns.
I also noticed that the current obs_lsst/config/lsstCam/filterMap.py maps LSSTCam filters to monster_ComCam_* fields.
Could someone clarify which Monster photometric columns and filter mapping were actually used for DP2 LSSTCam calibration? I understand that ComCam uses the same nominal ugrizy filters as LSSTCam, so I wonder whether this similarity is the reason for the current mapping. In particular, I would like to understand why there are no LSSTCam/SynthLSST columns in the_monster_20250219, even though the the_monster repository contains DES-to-SynthLSST colour transformations.
