[Rgc_analysis] question on asymmetry vs vz plot

[pilleux at jlab.org]

Dear Harut,

Please find attached the plots for the asymmetry distributions I get with
my ep->ep analysis, as a function of the z vertex, for NH3 runs 16726,
728, 744, 746, 750, 759, 762.

I attach a plot using the electron vertex, and one using the proton
vertex. The proton vertex is better resoluted (we get a more reasonnable
length for the target), but the statistical uncertainties are too large to
conclude for anything in my opinion. However, the two trends seem to agree
using the electron or proton vertices, with higher absolute asymmetries
around the center of the target. As you commented during last meeting, I
hope and think we will get better insights about this using higher
statistics.

Thank you. Best regards, Noémie.
