Hi,
I have a have a program that does some fits and plots and saves each result, including contours at various UP’s for parameter pairs. Every once in a while, while computing the contours, I get the following assertion:
MnMinos.cxx:92: ROOT::Minuit2::MinosError ROOT::Minuit2::MnMinos::Minos(unsigned int, unsigned int, double) const: Assertion `!fMinimum.UserState().Parameter(par).IsConst()' failed.
I haven’t been able to isolate what conditions cause it. I run Minos on the minimum to get error estimates prior to computing the contours and that does not raise this assertion (and the parameters I compute the contours of are fixed but not constant).
Any ideas?
Unfortunately, the assertion will interrupt the program completely, which is not ideal…
