Include qa note in both cases. Example:
** S band long sol int = 950s due to a pipeline bug. Manual calibration is advised. **

Background

The pipeline will occasionally produce a long solution interval on the order of 1000s. This happens when an 8bit setup is used two or more times, separated by a different setup. The sol int will span from the last phase scan of the first group to the first phase scan of the next group of same setup. This is related to combine='scan' in gaincal. In the worst cases, an additional effect seems to be that the pipeline somehow averages data between different fields.

Action items

  • We may rerun affected data sets once the new VLASS pipeline release is out, which should include the sol int fix. Record data sets here (beginning March 2022):
