W Scan and Rates
Rates Issue
There was a minor rates issue that occurred, not in the statistics, but in the maximum rate for past plots. They're all of the correct order of magnitude, but off by about 10% or so. It was causing the rates in the Rates plot (which was separated from the statistical uncertainty, which was correct) to come out slightly higher than they should have been. This has been corrected.
W Scan
Using incoming beam energy of 6.6 GeV and the optimized from earlier today, I did a scan over W to see how it affects the rates. The lighter colors are the total rates and the darker color (smaller rates) are with a W cut that starts at W<0 and increases to W<1.5
This gives us an indication of the contribution from:

Quasi-Elastic:
