[ROOT] Fitting with many gaussian signal riding on the polynomial background

Dear Rooters,

I wanted to fit many gaussians signals g1, g2, g3, .... riding on a 
polynomial background.


I started with the Laurentian + Polynomial at the tutorial section, and I 
was able to do the fitting with the LINE as the background. But I have to 
do it one by one (peak by peak within +/-5sigma of the peaks center).

But I wanted to do it with a Polynomial Background, so I will just do it 
once. 

How would the signal Function look like?
Any hint ?


Thanks.
