I added a few features to the existing JetMatcherAlg as well as JetHistoMatchedFiller in the offline MT JetMonitoring. Many of these were suggested in this post.
This includes:
Matching PFlow to EM jet (offline to offline)
Monitor not only the pT difference between matched jets, but also energy and mass difference as well as the responses for each variable. Additionally, we monitor the pT and eta of the reference (=offline) jets to be able to create 2D histograms in coarse bins of eta or pT. Note that I duplicated the configuration of the specifications & histograms for online and offline jets, so that we can configure them both individually, rather than having the same setup for both.
We are able to specify the calibration scale of the probed (=usually HLT) jets, so we can check different calibration scales. This could easily be extended/modified to have this feature also (or only) for the reference jets.
Before, the JetMatcher had a slight bug which caused it to sometimes match a jet to another one that had already been matched previously. This happened in 22 of 500 test events. This is now fixed.
Mini bonus: adding JVT relevant variables for chains that have a JVT selection (if relevant?)
