Spectral decomposition as a sum of sub-spectra
Sun, 04/17/2016 - 01:04 pm
I would like to fit a spectrum (Stot) as the sum of several sub-spectra (SA, SB) like Stot = (1-k) SA + k SB
All the spectra Stot, SA and SB are known. But in this case, there are no independent variables, there is only one fit parameter, k.
The problem seems very simple, but I'm at a bit of a loss as to how to fix it.
Thank you for advance for any advice.
PS : Stot, SA and SB have the same x scaling and are waves of same size.
