Well, yes, there was an attempt to use polarimeter but it was not successful. Showing it would give people a wrong impression that we had a polarimeter. It should be taken out.
As for the data presentation, if I would be in the audience I would definitely ask what is the uncertainty of the measurements. If I am to fit these data I need uncertainties.
If you leave it like this be prepared to explain what is the uncertainty.

Hi Louise,
Very nice slides.
Eugene is probably right, people might find the errors confusing, but I'd keep them like that and be prepared for the ensuing discussion..

Actually, if you get as far as showing the backup slides, we did have a pair polarimeter for g8. We made a couple of dedicated runs but there were problems with the hardware and low stats, and it wasn't used to determine the polarization.

Regards,
Ken

Louise,



A couple of things.

There is rather unusual presentation of data on slides 12 and 13. People used to operate with terms like statistical and systematic uncertainties. They would want to understand how to interpret this and get uncertainties in the traditional way.

On slide 18 you have “pair polarimeter”. There was no polarimeter in Hall B setup.

Dear Working Group members



Please find attached, for your information, the slides for a short contributed talk I will be giving at the International Nuclear Physics Conference being held in Glasgow next week.



The textual content of the slides is still work in progress, but the plots contained are the final ones to be shown.  I've submitted the talk to the speakers committee.



Regards,

Louise
