Eta dependence of shower shapes sorted into different preshower bins

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 )"

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

(I) Eta <= 1.4

(a) Pre1 =0, Pre2 =0

(b) Pre1 =0, Pre2 >0

c) 0<Pre1<4MeV

d) Pre1>=4MeV 

(I) Eta > 1.4

(a) Pre1 =0, Pre2 =0
