Gauss fit with pion, proton, electron

Minimum Pion Bichsel Curve

Pion Gaussian Set
Pion Sigma zero = 0.08688
Pion mu zero = 0.88153
I’m concerned about the electron curve. It does not look like it fits the data. I will add the Kaons to the Gaussian fit.
Should I do anything with the errors for the STD? It seems that the error of the purity and efficiency calculation will be largely based on the errors of my fits

Minimum Free Parameter Fit

Minimum Free Parameter Fit – Pos Amp

Efficiency, Purity vs. cut
![Page 12: Previous Work. Gauss fit with pion, proton, electron](https://reader034.vdocuments.mx/reader034/viewer/2022051401/56649d785503460f94a5b408/html5/thumbnails/12.jpg)
Efficiency and Purity Error
Is there an error in mu? Some error would be introduced because mu average is used. How should I handle this?
I used range of sigma0 for electrons and recalculated efficiency and purity (1.5<p<1.52)
