[Sane-analysis] Sane Meeting at 3:30pm Thurs Feb 12th in f227

[anusha at jlab.org]

Dear Oscar,
Yes, earlier calibration constants were included properly. I meant to the
correct calibration constant file. We didn't see much effect. However, may
be it had few MeVs changed. Will find those plots.

The E diff axis units on the plots are in GeV. I have using the proton
energy loss =ON for the simulation.

Best Regards,
Anusha
