      Description

      The values in the SAL messages from the pointing component that are used for the RASTART and RAEND headers are incorrect.

      Prior to about 2021-02-11T1845Z, they were in decimal hours and were offset by -37 seconds from the correct value (due to TAI/UTC).

      After about 2021-02-11T1845Z, they are in decimal degrees but are still offset by -37 seconds (of time, not of arc).

      It is expected that there will be a further change in the future to remove the offset.

      Please adjust obs_lsst to produce the correct values for this metadata.

      Tiago Ribeiro Please correct if I got anything wrong.
