keyword=retiming defined by S2-R. And T0 changePer request of Roy Holt, I modified the retiming circuit so that
it comes exclusively from the Right PMTs of S2 scintillator.
This means we should see good self-timing peaks on S2.
Below is the spectra for a cosmics run (1377). It looks pretty
good except for paddles 5 and 6 on L-arm. This might have to
do with paddle overlaps and the average angle of cosmics (???).
We'll have to see what happens with beam.
The (S1-R-OR).OR.(S2-R-OR) is still available and is
used by MLU strobe as before.
The timing offset (T0) did not change much. On a scope it changed
by less than 2 nsec. One should recalibrate it anyway.
