The decam and cfht gen2 test repos in testdata_jointcal are used in a variety of jointcal tests, as is a tiny "cfht_minimal" repo inside of `jointcal/tests`. Those need to be converted to gen3 so that jointcal can switch the existing tests to gen3.
This ticket is for just the conversion of the data, not for the test code itself. The existing HSC gen2->gen3 conversion code in testdata_jointcal will be a useful start for this, but may require some tweaking. DECam should be ok, but I don't know if anyone has tried converting a CFHT repo yet.
This ticket is for conversion of the CFHT data.
