I'm trying to fit data, which has not well-defined structure.
Since what i'm trying to do is QPA (PONKCS or Direct Derivation, ..) of these phase, (not conventional Rietveld method)
I want to describe the patterns with several single peaks (FP or PV), as accurate as I can.
But I can not get satisfying result, because I can not set independent broadenings in the same peak phase.
Here is my xo_Is lines.
xo_Is
xo @ 18.7069838` I @ 356.64851`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 34.8341628` I @ 183.33275`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 36.4538778` I @ 404.10218`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 37.2931326` I @ 338.83723`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 43.1649592` I @ 100.07022`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 47.6523145` I @ 413.45563`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 58.1318164` I @ 206.18202`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 61.8212588` I @ 497.64401`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 64.8310344` I @ 361.40465`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 74.1106624` I @ 138.65516`
peak_type pv
pv_lor @ 0.5
pv_fwhm @ 0.5
xo @ 76.9321569` I @ 71.99150`
peak_type pv
pv_lor @ 0.9921875`_LIMIT_MAX_1
pv_fwhm @ 0.559457313`
and this is after fitting, I can see that all the peak broadening is governed by the last one.
Is there any ways to work all broadenings independently?
