With the completion of DM-15751, you can now use jointcal’s output to build coadds. Once you’ve run jointcalTask on your data to produce the jointcal_wcs and jointcal_photoCalib datasets, you can build coadds as you normally would, setting the doApplyUberCal config option to True.
I’m announcing this here for those who aren’t following the epic about replacing meas_mosaic with jointcal for HSC (DM-11783).
Feel free to post any questions about using jointcal for coadds in this thread.
