Use MultiDomainFunction in IntegratePEaks1DProfile to share peak parameters across pixels #38439

Is your feature request related to a problem? Please describe. IntegratePeaks1DProfile seems to underestimate the error on the peak intensity image

This is possibly due to weaker pixels not being included as the fit is less reliable - as seen for this peak image

These pixels contribute more to the error than the overall intensity.

Describe the solution you'd like Use MultiDomainFunction in IntegratePEaks1DProfile to share peak parameters across pixels to make fit of weak pixels in particular more robust.
