Transverse Shower Profile Distributions

Old Fitting Function

Fitting function "[0]*(exp ( -0.5*((x-[1])/[2])**2 )+[3]*exp ( -0.5*((x-[4])/[5])**2 )+[6]*exp ( - 0.5*((x[7])/([8]*(1.0+[9]*(x-[7]))))**2 )"

New Fitting Function

Fitting function "[0]*(exp ( -0.5*((x-[1])/[2])**2 )+[3]*exp ( -0.5*((x-[4])/[5])**2 )+[6]*exp ( -0.5*((x[7])/([8]+[9]*(x-[7])))**2 )"
