TRD Likelihood Method: Fix histograms not being loaded properly
As described here https://redmine.cbm.gsi.de/issues/2601 the input histograms were not loaded properly since the change from h[i] = (TH2D*)histFile->Get(histnames[i]);
to h[i] = histFile->Get<TH2D>(histnames[i]);
. The proplem was that the input histograms were actually of type TH2F
. I changed this here to Get<TH2F>(histnames[i])
(and Get<TH1F>
for the 1D method)
