Please excuse my newbiness here, but I have some very basic questions on fitting signal plus background interactivley. First question, is there a way to set parameters to predefined functions (gaus for instance)? Next, is there a way to interactivley optimize the fit of this 'first guess'? This is motivated by common fitting methods in PAW. For instance to fit signal+background in PAW one would (for example) do somthing like: ve/cr p(7) r 120 1.860 .015 1 1 1 1 h/fit 222 g+p3 m 7 p and then inside minuit fix 2,3 mini impre Is there an anolog to this method in ROOT? Any examples or comments would be greatly appreciated. Thank you in advance Philip Borawski University of Texas at Dallas SLAC/BaBar Collaboration
