jbosch I chatted with K-T about raw_visit and raw_skyTile. He says that raw_skyTile is completely obsolete, so I removed all raw_skyTile entries from the obs_base datasets.
I also looked over registry.sqlite3 files for all of the mappers, and none has a raw_visit file which has columns which are not in raw and which are used by any datasets. Since at least in theory, raw_visit is derived from raw, I think it is safe to remove/replace raw_visit with raw.
I have added these changes since the review. Let me know if you approve.
Also, any changes which involve hand editing individual paf files will be moved to the
RFC-232-237, that is, the RFC for the individual mapper. I expect that all to be done next week. I've added an issue for those changes. This ticket is specifically to cover global changes involving obs_base.
