Project: common 
Subject: Trigger condition 
Run Number:  
StartTime: 4.10.2011 15:00 

Changed trigger such that off-spill scintillator triggers are vetoed.

Inserted Flip-Flop which is set by begin of spill (WWE) and reset by end of spill signal (EE). Out-bar is put in coincidence with the scintillator trigger.

This also changes the timing, which was unfortunately not detected until 30 hours later. Thus, runs 4-7 have bad (wrong) timing -> UNUSABLE
