[Clas_hadron] Baryons 2013 Talk for Stuart Fegan

[dugger at jlab.org]

I love it. An American could never get away with making such remarks about
Europeans.

Cheers,
Michael

> Hi Stuart,

> The slides look good. In reference to your talk from the Had Spec
> working group meeting - and only I'm allowed to say this - try to be a
> little less "Scottish" in the presentation. Maybe more Italian? Enthuse!
> Just a couple of, quite important, suggestions.
>
> On slide 19/20:
> You should fix the error bars as discussed yesterday to show that actual
> limits in cos theta - even if you have to just gimp  the plots.
> I'd say "Comparison with an preliminary data on an unpolarized proton
> target (g8b)". Don't say "older".
> I'd also remove the blue points, and phrase about "adjacent energy
> settings". This is just confusing and the comparison looks better
> without it.
>
> Slide 21. Again, fix the plots to get the "error bars" showing the
> actual range in cos theta.
>
> In presentation of slide 21. Focus on the positive. Something like this.
> "it's clear that there is a discrepancy in the results between the 2
> target settings. The most likely source of this is in the extraction of
> g, which is basically a small phase shift, using the binned fitting
> method. It is anticipated that using a moment analysis or event by event
> likelihood analysis will eliminate this problem.
> "However, the error bars are relatively small and indicate that a
> reasonable, first measurement of G for this channel will be achievable
> from this data, and will make a valuable contributions to the 1st ever
> complete measurement in pseudoscalar meson prod."
