coaddDriver was run with the ticket branch of
DM-12766, because otherwise it only worked with 1 core and would take 10-20 times longer.
In COSMOS tract 9813, the coadd products deepCoadd_calexp/deepCoadd_calexp_background/deepCoadd_det and deepCoadd_meas/deepCoadd_forced_src have 78 patches in HSC-G, 79 in HSC-I, 74 in HSC-R, 79 in HSC-Y, 79 in HSC-Z, and 75 in NB0921; in total 464 patches. The empty patches of tract 9813 are:
- patch 0,0 HSC-G,HSC-I,HSC-R,HSC-Y,HSC-Z,NB0921
- patch 0,8 HSC-G,HSC-I,HSC-R,HSC-Y,HSC-Z,NB0921
- patch 0,1 HSC-R,HSC-G,NB0921
- patch 0,7 HSC-R,NB0921
- patch 1,8 HSC-R,NB0921
- patch 8,0
- patch 8,8 HSC-R,NB0921
The results are different from w_2017_44/
DM-12388 (highlighted above). In the NB0921 band, the number of warps that "could not be created" (directWarp/psfMatchedWarp "has 0 good pixels") is higher compared to w_2017_44, leading to the one additional empty coadd patch at 0,1. The numbers of warps that could not be created are also different in other bands.
Products deepCoadd_measMatch and deepCoadd_measMatchFull have 461 patches in total in tract 9813; this is 3 fewer than other products as it missed all 6 bands in patch 0,1. The following message appeared in the log for HSC-I, HSC-Z, and HSC-Y bands:
multiBandDriver.measureCoaddSources.match: Matched 0 from 290/290 input and 7220/7220 reference sources
In WIDE, both tract 8766 and 8767 have all 81 patches of coadd products in all 5 bands.
The MultiBand products deepCoadd_mergeDet and deepCoadd_ref have 81 patches in WIDE tracts 8766 and 8767, 79 patches in COSMOS tract 9813.
