Basic coincidence time plots:
Figure 1 shows why we wanted the Aerogel: single arm TOF alone cannot
separate protons and pions. However, in a pinch, there is good proton-pion
separation in coincidence time. There is a little "toe" on the
e-pi coincidence time peak which is being investigated.
Figure 2 shows good separation of the RF bursts. Surprisingly, the rejection
of protons by this high Aerogel threshold is not that great, perhaps only
30:1. Something is fishy about this poor proton rejection, but it's good
enough.

Long term stability:
This figure demonstrates excellent stability of online coincidence time over
the run. It may be possible to accommodate this shift by simply using
two different windows for the coincidence time cut.
