The first 1,000,000 events from this run are analyzed. Configuration was "production2009_200Gev_Single / Physics"

The clusters are generated from Qtdata. These clusters differ from the "appended/internal" L1 DSM input clusters in two aspects. 1. Qt8 sums are NOT truncated. 2. The perimeter high towers are ignored according to Eleanor's table. 

Total of 40 clusters, one for each Qt32 board, are compared to the threshold.

LED suppression is done by looking at the number of channels with ADC>10, and cutting at 800.

Number of trigger breakdown per module based on software-appended L1 input.

North Large: Total 53283 triggers, top 5 cells produced 16% of the NL triggers.

South Large: Total 203106 triggers, top 5 cells produced 63% of the SL triggers. Ch454 generated over 110000 triggers.

North Small: Total 52290 triggers, top 5 cells produced 24% of the NS triggers.

South Small: Total 53090 triggers, top 5 cells produced 14% of the SS triggers.

Overall, 70.87% of the trigger came from large cells. There are minimal changes from day 151 apart from the increased dominance of South Large ch454. This is likely one of the cells with Zener problem.

For the following plots, the origin is South Up.

Pseudo Rapidity vs. Number of Triggers 

Attached spreadsheets show number of triggers, pseudo-rapidity, and phi for each cell. There is one for Qtdata based triggers, and another for L1 based triggers.
