[Frost] About Normalization

[Sungkyun Park]

Hi Eugene and Steffen,

Now I try to get the asymmetry plot for observable I^{circle} in FROST data to compare it with the data published by Steffen.
For this, I need to make the unpolarized target data from the FROST data.
I know each run has the target polarization with the same direction but their values are different.
To make unpolarized target data, I will divide each target polarization value.
Before doing that, I need to consider the normalization because each run has different number of events.

I make three picture in the following.
  http://hadron.physics.fsu.edu/~skpark/research/research_may2511.html
I will call picture-1 on the top left, picture-2 on the top right, and picture-3 on the bottom-left.
I made these using gflux056200_erg2.aXX.dat in our gflux. 

Q1) what do I use as the normalization factor in each photon energy bins?

picture-1 is about number of photons in each photon energy bin.
picture-2 is about (number of photons)X(photon energy) in each photon energy bin.

it I am on the wrong way, I really want to know how I get the normalization factor from gflux file.
