Hi Eugene,
For some reason this did not get to the FROST mailing list. I don't know 
why. Can you send it on.

On the topic of polarization. I'll respond to Franz's mail about banks 
etc for g9b cooking. We need to get the pol skims in the cooking. Mark 
will be back from Genova at the beginning of December. This should be 
timely for starting to work on the g9b polarization tables.

Cheers,
Ken

Hi Yuqing,
The tables from Mark are the ones to use. I've linked them and some
other documents on the frost wiki at
http://clasweb.jlab.org/rungroups/g9/wiki/index.php/Linear_Polarization_tables
(Also accessible on the Main Page)

It would be worth looking at the recently approved analysis note of Mike
Dugger
https://www.jlab.org/Hall-B/shifts/index.php?display=admin&task=paper_review&rid=9901989&operation=view

This has some details on how the systematics were dealt with, and some
references to the other documents.

Cheers,
Ken
