WeightProdSum Class Reference

Inheritance diagram for WeightProdSum:

Detailed Description

In HEP analysis, simulated events are typically weighted by various scale factors. and the actual "number of events" represented by a single simulated event would be product of all the various scale events. This plugin does just that: given a list of weight to use, calculated the product of all the weights, storing the per-event weight product, and also saving the sum of the weight product per run.

Constructor & Destructor Documentation

WeightProdSum()

WeightProdSum::WeightProdSum ( const edm::ParameterSet &  iConfig )

explicit

Construction expects the a parameter of type vInputTag, listing the doubles to be used in the product calculation. The weight product per-event would be stored under the label "WeightProd", and the sum of weight products stored at run level would be under the object label "WeightSum" (requires the usr::Counter class to read).
