keyword=helicity NON-problemSome evidence that the helicity info is not a problem:
1. In scalers it looks fine (a helicity problem would show up,
e.g. as a time diff of helicity to non-helicity in end-of-run).
2. Looks fine in Compton --> hardware at source ok.
3. If I analyze it with my private analyzer, I get the expected
pattern. See fig 1. This is for 200K events of run 2018.
One should plot with cuts as I showed, and do not exclude T9 in
the analysis chain (they are needed). But I'm not sure what is
being done wrong, I can only say the data look ok.
