keyword=alignment fine now. Will take out S0Run 3702 is to check the alignment.
Using S0 triggers.
We decide the alignment is fine (fig 1).
Actually it was fine before the first move. We are on
the elastic peak (X direction) and the envelope of Y is
larger than detector (but I think with 6 degrees and
septum the detector is big enough).
Run 3703 with a roughly 1:1 mix of S0 and thick PREX (T4) trig.
The resolution and pedestal width are pretty good already,
see fig 2.
Next step: Take access, remove S0 and do the 10 Hz stack
trigger test, but I bet that fig 2 doesn't change much.
