With the purely default config for HSC data, I got errors in reference catalog: 

lsst.daf.persistence.butlerExceptions.NoResults: No locations for get: datasetType:ref_cat_config dataId:DataId(initialdata={'name': 'cal_ref_cat'}, tag=set())

So, I'm adding config overrides as follows:

config.astrometryRefObjLoader.ref_dataset_name='ps1_pv3_3pi_20170110'

config.photometryRefObjLoader.ref_dataset_name='ps1_pv3_3pi_20170110'

config.astrometryRefObjLoader.filterMap={'B': 'g', 'r2': 'r', 'N1010': 'z', 'N816': 'i', 'I': 'i', 'N387': 'g', 'i2': 'i', 'R': 'r', 'N921': 'z', 'N515': 'g', 'V': 'r'}

config.photometryRefObjLoader.filterMap={'B': 'g', 'r2': 'r', 'N1010': 'z', 'N816': 'i', 'I': 'i', 'N387': 'g', 'i2': 'i', 'R': 'r', 'N921': 'z', 'N515': 'g', 'V': 'r'}

Oh yes, you'll definitely have to configure the reference object loaders. Using the same config as for single frame processing is probably correct, assuming that's what you did above.

I copied the configs from what you gave me before. For the filters in the HSC-RC2 data, they are the same as those in the single frame processing.

Why don't we include these config overrides in obs_subaru or some other places?

That's a good question: I don't know what the policy on config overrides is, but it probably depends on what we assume the default reference catalogs to be: the dataset_name and filterMap are going to be different for PS1 vs. Gaia, for example.

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 AlSayyad would know?

Anyway, w_2018_34's jointcal results is now available at this separate repo:
/datasets/hsc/repo/rerun/RC/w_2018_34/DM-15517-jointcal/
and the log files are at /datasets/hsc/repo/rerun/RC/w_2018_34/DM-15517/logs/jointcal.
I'll include jointcal for the future HSC-RC2 reprocessing too.

Hsin-Fang Chiang, our policy is to minimize the config overrides you need in order to run a DRP (and be internally consistent) so we will add these these to at least obs_subaru before w_2018_36.

Sounds great to me and +1 for adding these to obs_subaru. Thanks!
