The tutorial you talk about refers to a fit on all values with a sum of functions. What I would like to do is to fit with a function defined in different ways on different ranges:

            A/sin(x-x0)^4 x < sx || x > dx func =

            gaus sx < x <dx

Probably I'm missing something but I couldn't manage to do it.
