---+ G-Fact Mass Fitting ---++ Validation of signal fraction fitter (Lars) To validate the signal fraction fitter (aka mass fitter) a series of data sets were generated with different mixes of signals and combinatoric background were generated. Each data set has approximately 1000 toy data sets with 100k events each. All data sets are located in /data/lhcb01/eklund/B2hhToyData/, in sub-directories as given below. ---+++ Event mix: Bd -> π π, Bd -> K π and combinatoric background *Directory:* BdMix _561pipi_103Kpi/, 1000 data sets, 100k events each <table align="center" style="height: 150px;
