Transverse Shower Profile Distributions Sorted into Different Prseshower Bins - Triple Gaussian Fits (New)

Updated on Sat, 2011-07-09 19:35. Originally created by sdhamija on 2011-07-09 19:33.

 Transverse Shower Profile Distributions 

 

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+k*(x-[7]))))**2 )"

 

Figures on the left are shower profile distributions sorted into four preshower bins for the data and figures on the right are the corresponding distributions for MC.

To see the values of all the parameters for these different fits, please open the attached file shower.txt
