Hi,
When using the NLSF for fitting e.g. a Lorentzian function all the parameters are output with their respective variables. In addition the height of the peak is given automatically in the results log. Is the value of the height associated with any variable name? I want to have access to the height for further calculations.
Regards,
Espen

Hi Espen,
You are probably right, it is a strange version of the formula ... I find it best to define my own, by which you can get the parameters you want!
All the best,

Thanks,
Yes this is indeed one solution to this.
It should be 2*A/(PI*w), shouldn't it?

Hi Espen,
From the script window you can get any of the fitting parameters of the Lorentzian (Type "A=" to get the area etc.). From the formula the height is given by 2*A/pi. I do not know if there is a special variable for this but you can define your own with eg.
MyVariable=2*A/pi
Hope this helps!
