[GEM][Backport] Introducing GE21 rechit container for Run 3 by yeckang · Pull Request #50557 · cms-sw/cmssw

yeckang · 2026-03-26T08:23:30Z

PR description:

This PR enables saving the GEMRecHits from GE21 chambers, which are installed for testing purposes.
Currently, we are not saving them because of the possibility of interruption in the muon reconstruction performance.
However, several groups studying GE21 performance continue to ask if we can save them.
For this reason, GEM DPG decides to save them in a separate rechit container, which does not propagate to the muon reco system.

If this PR is a backport please specify the original PR and why you need to backport that PR. If this PR will be backported please specify to which release cycle the backport is meant for:

The original PR for the master is [GEM] Introducing GE21 rechit container for Run 3 #49476 and [GEM] [Bug fix] fix the flag in DQM for ge21 container #50556
The backport is needed for using the feature during the 2026 data taking

What is this removal about? It does not seem part of the master PR?

Oh, maybe I made a mistake when I copied the file from the old workspace. I will revert and push it again
