[clas12_rgk] First look at RG-K 6.4 GeV production data

[Sangbaek Lee]

I also produced similar plots for the DVCS channel.
All look reasonable to me, but it'll be nice if someone can cross-check the distributions.

slide 1: overview of the data sets I used (I tried to used the same data sets with Daniel), and some cuts made beyond the skim 16.
slide 2: Q2-xB phase space
slide 3: t- phi phase space
slide 4–10: exclusivity variables
slide 11: cone angle between the scattered electron and the produced photon (to estimate the radiative effects).

Best regards,
Sangbaek
