Re: Corrected: Sensitivity vs Far Detector Systematics

Dear Mike,

There is a lot of good information in your plots
but perhaps even too much. I wonder if a more
direct statement wouldn't be a plot of
sensitivity vs distance for the nominal dm2
together with a band corresponding to +/- 1 sigma
in dm2. I'd just stick to the combined
sensitivity from the two methods. I think the
committee wants to capture a simple number to
characterize the dependence on distance.

You might consider such a plot together with the
more detailed information of these plots you have
already prepared.
