Hello,
This MR is adding HLT tau track impact parameters and significances (4 new floats per track) to the Run3 trigger EDM file, for one container (HLT_tautrack_MVA), so that these variables are available in AOD.
These variables are dynamic variables that will be needed to train RNN tau ID for Run3 tau triggers: d0TJVA, d0SigTJVA, z0sinthetaTJVA, z0sinthetaSigTJVA.
The others in the list are static Aux variables that were already kept by default.
The only Aux variable not appearing in the list is bdtScores, which is no longer used in R22 (neither offline nor online).
From 40 q221 events,

74.975 kb 12.182 kb 0.305 kb 0.000 40 (B) HLT_tautrack_MVAAux.Hopefully the size increase is acceptable.
For completeness, I have updated the q221 digest reference file to reflect the new AOD content, although currently the CI test seems to ignore the L1 and HLT trigger content. I guess that's why people don't bother updating this file when the trigger content changes, and must explain why non-tau trigger changes are reported.
Tagging @ademaria , @iriu , @okuprash .
