Notes from talking with Simon Krughoff:

• validation_data_hsc should be deprecated, as it is not used by the verification team for anything.
• faro is run on rc2_subset via a script in the bin directory there. This just runs pipetask on the obs_subaru DRP.yaml.

I should reorganize the validation_data datasets (assuming we're still going to use them, which might not be feasible!) to have the necessary scripts/configs in them.

A guess at the necessary steps to run on the decam/cfht validation datasets:

• Find out if anyone has a working DECam/CFHT DRP.yaml, and how much does it look like the obs_subaru one?
• Make a gen3 repo that contains the raws/calibs/refcat/skymap.
• Decide whether to always assume the repo is clean (i.e. a new Jenkins checkout every time) or whether to export/import the repo to be able to run repeatedly. The latter would be more future-proofed (like how testdata_jointcal is used for testing), but might be harder to actually do (e.g. calibrations).
• Run `pipetask REPO obs_subaru/DPR.yaml#step1` and see what happens. We'll almost certainly have to override that for DECam.

As part of this, we might want to move the CFHT defects out of obs_cfht, and into an obs_cfht_data, to match our convention on that.

Simon Krughoff: do you mind reviewing these two tickets? It's about 80 lines of changes in obs_cfht to get it to work in gen3, and a bunch of changes and removals in validation_data_cfht demonstrating that we can run a gen3 singleframe pipeline on it. I did the minimum I thought was necessary to get jointcal to run on this data, so if you want to run faro on this output, you'll need to make more changes.

The commits should all be atomic, which should make the validation_data_cfht changes easier to view, since I changed lfs files.

Very sorry for taking so long to get to this. It all looks good. Tim has a comment on obs_cfht that I think you should consider
