### Summary When I try to run ```console $ pyhf cls --test-poi 0.16 signal.json ``` (file provided to developers) with pyhf, the result depends on the version. For versions before...

getMCShowerType fails on Sh_228

1

The getMCShowerType function (https://github.com/UCATLAS/xAODAnaHelpers/blob/main/Root/HelperFunctions.cxx#L520) doesn't cover all samples. In particular, the sample mc20_13TeV:mc20_13TeV.700000.Sh_228_ttW.deriv.DAOD_PHYS.e7793_s3681_r13167_p5631 (corresponding to Sherpa 2.2.8p3) returns an Unknown. This cases processing to fail in https://github.com/UCATLAS/xAODAnaHelpers/blob/main/Root/BJetEfficiencyCorrector.cxx#L245 . Should Sherpa...

Custom MET Significance Muon Calibration

3

The MET significance handler (https://github.com/UCATLAS/xAODAnaHelpers/blob/main/Root/METConstructor.cxx#L143) doesn't allow the muon calibration tool to be set, forcing it to use the default. This gives a warning at https://gitlab.cern.ch/atlas/athena/-/blob/master/Reconstruction/MET/METUtilities/Root/METSignificance.cxx#L157 , and may not...

The BJetEfficiencyCorrector (https://github.com/UCATLAS/xAODAnaHelpers/blob/main/Root/BJetEfficiencyCorrector.cxx#L486) does not set a SF for jets with abs(eta)>2.5 if dec_sfBTag is available. Using the MC20 file "xAODBTaggingEfficiency/13TeV/2022-22-13TeV-MC20-CDI-2022-07-28_v1.root", the decoration is available for jets with abs(eta)>2.5, returning...
