[G12] MC TOF Resolution

[Michael Kunkel]

But kaon people should show this. I would suspect that lepton timing is a bit broader than kaons, so a tighter cut is good.

But for people analyzing kaon data, I suspect that are using a tighter timing cut, and this MC/data resolution discrepancy should be taken into consideration, if they are doing any kind of acceptance correction and cross section calculations.
