Detailed Description

Helper class for the calculation of a top and a W boson mass estime.

Helper class for the calculation of a top and a W boson mass estimate. The core implementation originates from the plugin TtSemiLepHypMaxSumPtWMass in TopQuarkAnalysis/TopJetCombination package. It may be extended to include b tag information.
