L2W algorithms used as a filter to reduce the event yields getting into the st_W data stream from the raw L0 hardware EHT1 triggers.
For the endcap W we use EHT1*L2EW trigger, the endcap trigger look for a single tower(EEMC) with ET > 10 GeV.
top: ET of the most energetic endcap tower in the event for all events
bottom: distribution of most energetic endcap tower in events which satisified the trigger vs tower RDO (unique identifier).
use ET Thresh =9.200000, RndAcceptPrescale=80
