As I'm just starting to include jointcal this week, I think you and the Science Pipelines team can decide the best configs and change the default in the Stack in the short term without problems from my side. I don't know if there are policies internal to the Science Pipelines team; maybe yusra would know?
Anyway, w_2018_34's jointcal results is now available at this separate repo:
and the log files are at /datasets/hsc/repo/rerun/RC/w_2018_34/
I'll include jointcal for the future HSC-RC2 reprocessing too.
