Abstract: meh.
Figure 1 -- Baseline isolation setup. No fiducial cuts, toy model leakage correction.

Currently we are having problems when reconstructing events near sector boundaries. (eg part II). In figure 2, we apply a +/-1.5 degree fiducial cut at sector boundaries. This will sacrifice 10% of our acceptance.
Figure 2 -- Baseline correction, +/- 1.5 degree fiducial cut (10% acceptance loss) at sector boundaries.

hmmm no obvious improvement here...
Ok, I've tried several things at this point and haven't made a break through. I'm declaring victory at this point using the baseline correction scheme. i.e. I've found "few %" not "10 percent" improvement at best for significant additional work.
