I want to make a spectral correction curve of my light source to resemble the Gaussian spectrum.
This literature said,
".. The dashed curve is a Gaussian fit with a center wavelength of 833 nm and a FWHM of 49 nm to the spectrum, determined by the zeroth, first, and second moments of the spectral density. The ratio of this ideal Gaussian source spectrum and the measured spectral density defines a spectral correction curve, SC(lambda). "
Tripathi et al., “Spectral Shaping for Non-Gaussian Source Spectra in Optical Coherence Tomography.”
( https://escholarship.org/uc/item/7gh8k6hc )
All I have done is calculating the moment of my spectrum data with MATLAB command "moment(x,n)".
However, I cannot get any clue after this step.
Where should I start first?

Actually I already tested cftools.
It can generate the Gaussian fit, but I cannot relate this fitting curve with the 'moment' of original data.
Is there something that I missing in theoretically?
