CMSSW Phase-2 geometry numbering
The various Phase-2 geometry descriptions are documented in Configuration/Geometry/README.md.
Available RelVal workflows for all geometries can be found by doing
runTheMatrix.py -w upgrade -n. (The possible
-w arguments are listed in Configuration/PyReleaseValidation/python/).
Related to this, the various pileup scenarios are detailed in Configuration/StandardSequences/python/Mixing.py. The ‘auto’ conditions are detailed in Configuration/AlCa/python/autoCond.py. The ‘era’ parameters are detailed in Configuration/StandardSequences/python/Eras.py.
For Phase-2 L1T Upgrade TDR studies, I used geometry
