Figure 1 shows the coincidence time spectrum for T6.  The plot is from run
2037 for the 450 MeV/c elastic protons.  For this plot, I have also placed 
and elastic electron cut on the left HRS variables.  Figure 2 shows the
comparison of the T6 spectra for the 350 MeV/c and 400 MeV/c wrt the 
450 MeV/c protons.  I did not place a cut on the elastic stripe for these
curves.

I expect about a 3 ns shift in TOF between the red and blue curves, but
it is hard to see due to the timing resolution.  The black curve is shifted
from the red by about 5 ns, and the expected value is 6 ns between the
350 MeV/c protons and the 450 MeV/c protons.

The T6 coincidence trigger appears to be working well.  Please look closer
at the data and let me know if there are any problems.
