Ok, using your ticket branch, I ran:
mosaic.py /datasets/hsc/repo --rerun RC/w_2019_14/DM-18300-sfm:private/lauren/DM-19265 --numCoresForRead=12 --diagnostics --diagDir=/scratch/lauren/DM-19265/mosaicDiag/ --id tract=9813 ccd=0..8^10..103 visit=1228..1232:2^1238..1248:2^19658..19662:2^19680..19684:2^19694..19698:2^19708..19712:2^30482..30504:2 filter=HSC-I
The following is the comparison of this output to that of the w_2019_10 RC2 run for visit 1228 (meas_mosaic calibrations being applied here):
So the good news is that the Jacobian is back Puzzling, though, is that there is still some difference between this branch and the w_2019_10 RC2 run. In fact, this difference also exists (in spirit) for the w14 vs w10 jointcal calibrations:
Comparing w10 to w06 meas_mosaic looks like:
which again show similar – but not identical – differences. Here is the same comparison but between the w10 vs w06 jointcal calibrations:
So it seems there have been some subtle changes from weekly06-to-weekly10-to-weekly14 that slightly affect the uberCal results. I had a glance at the weekly changelogs and nothing in particular jumped out at me. Any ideas? If this is expected, then no further digging is required...otherwise we may need to figure out the source of these differences (however small?).
