I’m trying to create a macro that finds peaks in a histogram, and then is able to fit them with a specified fitting function. I need to do this a lot, so I need a useful peak-search method. Searching around points me to the TSpectrum class, and it is quite trivial to search for peaks with this. Howe…

This issue has now come up many times without a definite answer from the core development team, so let me give you my 2 cents. The team wants to consolidate the number of algorithms for fitting and unfolding in ROOT. One of the candidates to replace is TSpectrum with appropriate code using RooFit a…
