[Frost] About beam and target polarization of the linear data

[Michael Dugger]

Sung,

For target polarization you can use the ExpTable code described at:
http://clasweb.jlab.org/rungroups/g9/wiki/index.php/Rootbeer%2C_including_eloss_and_ExpTable

Once you have ExpTable working you can get the target polarization like 
this:

g9Table->GetAllForValue(runNumber,"Run");
tar_pol = g9_TPol;

For the linear photon polarization you should look at Ken's preliminary 
linear polarization web page at
http://clasweb.jlab.org/rungroups/g9/wiki/index.php/Preliminary_Linear_Polarization_tables

I hope this is the information you want.

Take care,
Michael
