First Compton asymmetry history at 4 passes (see attached picture).
So far, the measured beam polarization at 4 passes is 67.11 +/- 0.25 %. The measurements are pretty consistent with each other.
FYI, the macro which allows to make this simple plot is in:
/home/compton/franklin/anal/runeric
The name is AsymmetryHistory.cpp, it includes the routine PlotAsymmetryHistory which takes for input the number of passes N considered, and the corresponding datafile AsymmetryHistory_NPass.dat,
which has to be kept up to date.
