The current issue of Normalization Factor (Aug 11 / 2011)

In circular polarized beam data, there are seven groups, which have similar conditions (target polarization, 1/2 wavw plate status)
We have defined them as the periods.
To get the normalization factor in g9a, we have checked the number of photons in gflux files and the number of events in g9a Table per each period.


The red line - the number of photons in gflux files per periods
The black line - the number of events in g9a Table per periods
The red point - the number of photons in gflux files per periods and energies
