[Frost] target polarization

Hi,

I would like to have a FROST approved list of target polarization 
directions for g9a on a run by run basis.

I have been looking at the "Helicity assignment for g9a" web page at
http://clasweb.jlab.org/rungroups/g9/wiki/index.php/Helicity_assignment_for_g9a
and see different results!

Brian has told me that I might want to use Steffen's list, but I am 
concerned about the comment:
"The asymmetry of the 1.645 GeV data has the opposite sign without an 
additional sign change. This sign change needs still to be understood."

We need one single FROST approved list. Does this list exist?

Thanks for your time.

-Michael
