////// 4/16/15 Changed the definition of dstar mass to that of angelo's ////// 5/21/15 Added MC tunings for RBW, updated RBW and verified it does the right thing. Finally, there was a bug in the mass calculation since moving to Angelo's definition, I did no update the beta star cuts to include the K and pi daughters, so all the cuts were on the constrained mass. That has been fixed. /////// 6/15/15 Changed betastar to take a name variable to avoid memory leaks with histograms. ////// 6-16-15. Added complete anlysis code to github ///// 10-21-15: The only way to shut up augusto is to redo the whole analysis unbinned. This involves switching to a roo dataset to get things right
