As suggested by @khoo, we want to take a look at the basic PFSum algorithm using PFOs with constituent subtraction applied. The best subtraction method available is CSSK (constituent subtraction + soft killer) but this is somewhat slow so an implementation for VSSK (Voronoi + soft killer) is also included. This MR makes the following changes
JetRecoConfiguration.defineJetConstit
is modified to allow VoronoiMETRecoSequences
are modified to allow applying constituent modifiers (supplied by a new constitmod
key in the SignatureDict)Tagging @bcarlson for info.
