Slope from the function "bigaus"

caforioroot · September 17, 2021, 2:17pm

Hello,
I have an ellipse-shaped distribution in a 2D histogram that I want to fit with the “bigaus” function.
The fit works very well, but I need the slope of the resulting function: is there a way to get this parameter?

With thanks

Davide

Hi,

For the slope, do you mean the correlation parameter of the bigaus ?
It is the parameter with name Rho (Par[5]) of the bigaus function.

Sorry for the late reply
