Now that jointcal applies the colorterms, we can look at much smaller differences in how meas_mosaic an jointcal match the to reference catalog. Some observations. There is a shift that jumps from
- from 3 to 5mmag in HSC-I meas_mosaic_I vs. jointcal_I
- 6 to 12mmag in HSC-R meas_mosaic_R vs. jointcal_R
- 8 to 8mmag (no change in HSC-G!) meas_mosaic_G vs. jointcal_G
and the 3 mmag shift in the `w` principle component from jointcal to meas_mosaic new_jointcal_gri which is probably a manifestation of the offsets above (and just another way of looking at it)
I don't know if these are significant or not. Will those with more expertise comment on whether this is a problem or not.
NOTE: these comparisons were done with meas_mosaic before
DM-13054. If https://community.lsst.org/t/incorrect-reference-magnitude-errors-from-photocaltask/3581 affects meas_mosaic too, I propose we wait for Hsin-Fang Chiang's w_2019_06 run next week before we spend time thinking about this.
