Entry number 55073

From: R. Michaels
To respond to halog 55042, the events at (-1, 1)
mean there's a hit on S2 scintillator paddle 1 but
nothing on S1 within time cut (350 < t < 3500).
You can see them with dataspy (example below).
As I noted while on shift, e.g. halog 54891, the
present simple overlap trigger appears to have
more background than the old S-Ray mlu for the
present setup.
