keyword=re: self-timing.
Yesterday we adjusted the self-timing peaks to appear on S2-R.
But this was done for COSMICS. I guess we forgot that cosmics go
down but beam goes up. The delta-T between these cases is 14 nsec.
So we can make self-timing on S2-R by adding some more delay to S1.
Note, if the self-timing comes from S1 it might either be L or R
because we didn't split those. None of this is really a problem
but it is convenient and less of a headache for self-timing to
appear on one bank of PMTs.
