call_func(events, muon_mask=Ellipsis, **kwargs)

Creates muon weights using the correctionlib. Requires an external file in the config under muon_sf:

cfg.x.external_files = DotDict.wrap({
    "muon_sf": "/afs/cern.ch/work/m/mrieger/public/mirrors/jsonpog-integration-9ea86c4c/POG/MUO/2017_UL/muon_z.json.gz",  # noqa
})

get_muon_file can be adapted in a subclass in case it is stored differently in the external files.

The name of the correction set and the year string for the weight evaluation should be given as an auxiliary entry in the config:

cfg.x.muon_sf_names = ("NUM_TightRelIso_DEN_TightIDandIPCut", "2017_UL")

get_muon_config can be adapted in a subclass in case it is stored differently in the config.

Optionally, a muon_mask can be supplied to compute the scale factor weight based only on a subset of muons.
