+1

• This adds the parameterizations needed to compute the L1 muon prefiring rate, which will be used by #33758
• The added file is not required by any other CMSSW module before merging #33758, and therefore merging this external in advance with respect to that PR won't affect any current workflow, while it will help testing it in more detail

can this be merged ? the test in cmssw#33758 pass successfully
