Wrong fit parameters

Hi, I have a script that fits some points using a function. The problem is that root is printing wrong parameters (and i suppose that errors are wrong too) of this function (when i plot the function with the given parameters, the plotted function is different from the one that fits the points). Is there any way to print properly the parameters of the fit function?

Hi David, is it possible to submit a small piece of code that reproduces your problem. Reading your post, could it be that you assigned your parameter values incorrectly ?
