<p>Another milestone in the trigger algorithm testing with
a beam.</p>
<p>Cluster finding:<br>
1. Hits are required on both ends of a long bar (single
hit for short bars)<br>
2. A coincidence of at least one horizontal and one
vertical bar is required to<br>
produce a trigger.</p>
<p>In the plot below, a coincidence is searched between
any of 5 vertical and 5 horizontal<br>
bars in the upper right corner of the TOF, i.e., in
every event there should be a space<br>
point (coincidence of paddles) in the upper right
corner.</p>
