Changed Sequence Numbers
In the past, when observations needed to be split (for instance, a
partially completed observation had to be continued with different
ACIS chips), a new ObsId with a new Sequence Number was created.
We have changed that policy and currently a new ObsId with the old
Sequence Number is created. In order to facilitate uniform
bookkeeping, we are now changing the Sequence Numbers of past
observations for these split cases so that the current policy will
appear uniformly applied since the beginning of the mission. This
way, different pieces of the same observation can always be tied
together by their common Sequence Number.
We have posted lists of ObsIds that had their Sequence Number changed,
accompanied by their parent ObsIds, separately for
