TauAnalysisTools: fix irreproducibility in tau smearing tool (PHYSLITE re-calibration) (!50078) · Merge requests · atlas / athena

Bertrand Martin Dit Latour requested to merge martindl/athena:R22_TAT_PHYSLITE into master Jan 31, 2022

Hello,

This MR fixes an irreproducibility issue discussed in ATLASG-1620. When applying the tau smearing tool (i.e. in-situ TES correction) several times to MC, the TES correction is applied several times because it is applied to "pt" (which drifts as corrections are applied) instead of a fixed reference pt (ptFinalCalib, i.e. MVA pt coming out of the reconstruction).

I also spotted a similar problematic behaviour in a functionality that is currently not used by default. To be fixed.

Tagging @schaarsc and @ghamity , as well as @qbuat , @dta , @ademaria , @vimartin , @lheinric for information.

Cheers, Bertrand
