This MR adds four moments to small-R jets that are needed to derive systematic uncertainties on the jet mass scale. Instead of adding all ghost-associated tracks of small-R jets to the derivations (JETM1 is already very large and this would increase the size significantly), this MR directly calculates the invariant mass of these ghost-associated and also for the systematically varied tracks. This adds four floats per jet.
