The obs_lsst LATISS metadata translator assumes that data after RASTART_IS_BAD is off by 37s, but in fact this was fixed on 2021-02-12. Please fix the metadata translator.

I'd do it myself, but I don't understand the comment

# RASTART/DECSTART/RAEND/DECEND used wrong telescope location before this

# 2020-02-01T00:00 we fixed the telescope location, but RASTART is still

# in mount coordinates, so off by pointing model.

RASTART_IS_BAD = Time("2020-05-01T00:00", format="isot", scale="utc")

and would prefer you to clarify that the problem being fixed is not this one.

There is a more serious problem too, namely that the correction of c. 0.154167 is applied multiple times. The RAEND in the header is 130.211695172908, but:

exposure.getMetadata().get("RAEND"), butler.get("raw_md", dataId).get("RAEND")

(130.82836183957568, 130.36586183957567)
