hi john,
i'm pretty sure the big spike around TOF 12 corresponds to the gap
between TOF's 3,4. i just talked with chi about the possibility of
adding a couple of variables "swl,swr", which would be floats between
0-16, projections of the wc track to the relative position where it
crosses the tof's. (3.5=middle of TOF 3) with this in hand, we could do
the sort of thing you are thinking about. i just need the extra time
(or help?) to add this.
another improvement would be to cut on the CC or NC (especially for
the right sector!)
