Run 7797 malfunction
The data of run 7797 is stored in the 7798 data files.
Also the event identification of 7797 is set to run 7798, so reading files :
$ ls -1 /eos/experiment/na64/data/cdr/cdr01*-007798.dat
/eos/experiment/na64/data/cdr/cdr01001-007798.dat
/eos/experiment/na64/data/cdr/cdr01002-007798.dat
/eos/experiment/na64/data/cdr/cdr01003-007798.dat
/eos/experiment/na64/data/cdr/cdr01004-007798.dat
/eos/experiment/na64/data/cdr/cdr01005-007798.dat
/eos/experiment/na64/data/cdr/cdr01006-007798.dat
/eos/experiment/na64/data/cdr/cdr01007-007798.dat
you will see the event sequence run-spill-event like:
7798-1-1 - event timestamp data corresponds to 7797
7798-1-2
..
7798-200-1
...
7798-1-1 - event timestamp data corresponds to 7798
7798-1-2
..
7798-200-1
...
The daq logs indicate the 7798 is the only run with total number of spills > 200, but more detailed check is necessary to verify if there are other runs with the same problem.

The action items of this issue:
-
Check the distributions of cdr01*-007798.dat to decide if these files are good for physics. -
Check all data of 2022B for this issue, normaly event ID run-spill-event should be uniq. -
Patch event ID data in problematic .dat files and split/rename original .dat files with proper file name.
