With the shared stack changes , the default stack at /software is now Python 3. This ticket is the first biweekly RC reprocessing with the Python 3 Stack.

We do have to remember that we know of at least two occasions where py2 and py3 disagree and we haven't looked into why yet.

Yes, they are DM-11779 and DM-12180. I asked in Slack #dm-hsc-reprocessing and the consensus was it's okay to move on to Python 3. (tagging Jim Bosch John Swinbank )

(Also, being totally picky, I did look into DM-11779, I just failed to achieve anything useful!)

SingleFrameDriver/prcessCcd failed in 12 CCDs at WIDE, and 17 CCDs at COSMOS. Their data IDs are:

Out of the 29 singleFrameDriver/prcessCcd fatal failures:

• 14 failed with "Unable to match sources"
• 4 failed with "No objects passed our cuts for consideration as psf stars"
• 11 failed with "PSF star selector found [123] candidates"

A log with the 29 processCcd failures is attached: log_w44_retryFailedSfm-99756.out

In COSMOS tract 9813, the coadd products have 78 patches in HSC-G, 79 in HSC-I, 74 in HSC-R, 79 in HSC-Y, 79 in HSC-Z, and 76 in NB0921; in total 465 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
• patch 0,7 HSC-R,NB0921
• patch 1,8 HSC-R,NB0921
• patch 8,0 HSC-G,HSC-R
• patch 8,8 HSC-R,NB0921

In WIDE, both tract 8766 and 8767 have all 81 patches of coadd products in all 5 bands.

The MultiBand products have 81 patches in WIDE tracts 8766 and 8767, 79 patches in COSMOS tract 9813.

This is the same since w_2017_28 (DM-11184).
