patch indexing for (de)selected weights (!160) · Merge requests · Cedar / Rivet

Christian Gutschow requested to merge fix_deselection into release-3-1-x Jul 28, 2020

This fixes an issue reported on the ATLAS Rivet list where the weight indices might get messed up when (de-)selected a subset of the weights.

At the same time, I've made the Event class aware of the indices corresponding to the surviving weight subset and let it strip out deselected weights (as opposed to the AnalysisHandler doing that like before). This simplifies the code in some other places, notably MC_WEIGHTS and MC_XS.
