Hi Jack, First, a clarification: mn_fit is not in PAW. mn_fit is an interesting subset of PAW with added functionality for fitting. The author Ian Brock did a very nice job. The functionality you describe in your mail does not seen very difficult to add to ROOT/Minuit. Just note that with 3.02, you can - fix one or more parameters - fit over non-contiguous bin ranges It would be nice if Ian could collaborate with us to extend ROOT fitting as he did in mn_fit. I will see with him. Rene Brun On Wed, 9 Jan 2002, Jack Cranshaw wrote: > Hi All, > > There are quite a few people here at CDF who use mn_fit for > fitting histograms.
