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

Pion, Electron, Kaon, Proton Fit

Electron Sigma zero = 0.08671

Electron mu zero = 1.31032

Pion, Electron, Kaon, Proton Fit

Kaon Sigma zero = 0.07388

Kaon mu zero = 1.5986

Pion, Electron, Kaon, Proton Fit

Proton Sigma zero = 0.07235

Proton mu zero = 1.71444

Minimum Free Parameter Fit

Minimum Free Parameter Fit – Pos Amp

Efficiency, Purity vs. cut

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)
