Is it possible to get the TAE index from ODIN?

There is a function ODIN::timeAlignmentEventIndex() but it returns the TAE half window size instead of the TAE index (see e8bc01ab).

I would expect the TAE index to be an index from 0 to 2*half window+1 (or shifted to be centered around 0).

Currently, we reconstruct the TAE index using a list of isolated bunchIDs provided in the optionsfile, which is fine for offline analysis but we have not yet found a nice way to do the same for the online monitoring.

The settings of the ODIN firmware were changed early in 2023 to write the index instead of the half window into these bits. I cannot tell you exactly when but it was shortly (up to 10 days?) after https://lblogbook.cern.ch/Shift/16660 . Please reopen the issue if it's important to know exactly when this was changed.
