[G14_run] [EXTERNAL] Re: Analysis note on the extraction of G and Sigma polarization observables for pi-p photo-production on quasi-free polarized neutron

[Bryan McKinnon]

Dear Annalisa

Do you have any update as to the progress of your g14 internal review?
The analysis review committee are eager to get started.

Regards
Bryan

Results on Sigma asymmetry are compared with the ones obtained from g13 data, for consistency checks. The results on G asymmetry are the first ever obtained.
