Install fgcmcal look-up table in shared repos (e.g. /datasets/hsc/repo)


    • Type: RFC
    • Status: Implemented
    • Resolution: Done
    • Component/s: DM
    • Labels:


      With DM-23331, default fgcmcal configs are in obs_subaru. Therefore, the associated look-up-table (which fgcmcal uses to approximate the atmosphere and instrumental variations) can be installed in the shared repos. The look-up-table describes the full range of atmosphere variability possible at Mauna Kea, as well as information on the spatial variation of the g, r, r2, i, i2, z, y, N387, N816, and N921 filters that were recently installed in DM-23254.

      Generation and installation of the look-up table is done by:

      setup fgcmcal
      fgcmMakeLut.py /datasets/hsc/repo |& tee make_fgcmcal_lut.log

      Note that the above path is to the regular data repository root, not a calibRoot; the look-up table is not yet versioned.

      As per our policy on modifications to /datasets:

      • Description and reason for addition/change/deletion: The new datasets enable fgcmcal photometry to be run without the step of generating a look-up table.
      • Target top-level-directory for location of addition/change/deletion: /datasets/hsc/repo
      • Organization of data:
        • Look-up table will go into /datasets/hsc/repo/fgcm-process/
      • Other necessary domain knowledge as identified by project members relating to the contents of the data: See https://github.com/lsst/fgcmcal/tree/master/cookbook for more information on the FGCM look-up table.
