If this variable is set the code will open the file with same name as the file created here and will read the binning from the TH1/TProfile with same name as the one created here.

If you do not want this feature either remove the corresponding root files from the validation directory (this will trigger the default behaviour) or set the environmental variable DO_NOT_READ_BINNING
