Re: Simulation report is released




HI Andrei,

Thanks for the reference.

To normalize to your MC, I have the following factors:

From your 2 GeV data Npe(right) = 6550, Npe(left)=5383.  These are close
to the center so I take the average = 6000/side/2GeV = 3000/side/GeV

For the SiPM option I get an averge of 1575 Npe/side/GeV (0.52*MC)
For the FM option I get an average of 410 Npe/side/GeV (0.138*MC)

To scale to the "end" of the module, I scale by an attenuation length
factor to 20 cm from the edge of the module.

Assume attenuation length of 350 cm, to get the extreme limits, I use the
following factors:

For the 20 deg data, shower is at 227 cm from the upstream end, 163 cm
from the downstream. To scale to 20 cm to the downstream end I use
e(143/350)=1.5 (downstream) and e(-143/350)=0.66 (upsteam)

For the 90 deg data, shower is at 48 cm from the upstream end. To scale to
20 cm from the end, I use e(28/350)=1.08 (upstream) and e(-28/350)=0.93
(downstream).

Cheers, Elton.
