Hello
Extremely lorentzian peaks can be fitted by adding twice the same str with individual (small and large) fwhm parameters while constraining e.g. lattice parameters etc.
Is there a way this can be done by using only one str?
Cheers,
Martin

There are a few ways to get Super Lorentzian's
1) Use the PVII peak type and set m=2. PVII peaks however have additional Lorentzians and Gaussian convoluted numerically.
2) Maybe a str dependent emission profile (Note emission profile can be str dependent) with two emission profile lines at the same wavelength.
3) Use two structures like you have done
