21.9 - Fixing cuts to be compatible with ITk Inclined Duals in 20.20.10.7

While checking the loss in track efficiency, I have compared the log files obtained in 20.20.10.7 for the Inclined Duals reconstruction and I have found a mistake in the configured reconstruction cuts in 21.9. My bad, I guess I have copied the wrong configuration and I didn't figured that out so far. You can check the diff of this MR.

I have run the test comparing 20.20.10.7 against 21.9 with the correct cuts and the situation improves: https://test-dcube.web.cern.ch/test-dcube/physval_checkCuts.root.dcube.xml.php

I guess we should as well update the vertexing cuts which are not important for single muon jobs. Below you can find the cut configuration as obtained in 21.9 vs 20.20.10.7:

Can others please comment before removing the WIP prefix? @nstyles, @asalzbur, @xai, @npetters, @lmijovic, @goblirsc, @swaban

changed the description

Hi @ncalace,

Great that you found this! The efficiency indeed looks much better, so no objections from my side to moving this out of WIP.

Regarding the vertexing cuts, I guess we can just take the 20.20 cuts directly for the moment. These are 'flat' cuts with no eta track eta dependence?

Yes, they are flat cuts. I'm not aware of eta dependent cuts, but I can be wrong, so better checking with @npetters, @lmijovic and @goblirsc.

For the sake of clarity, I'm going to remove the WIP prefix and make another MR for the vertexing cuts.

Cheers, Noemi
