Run 10123004 (5/3)

 

I'm looking at the first 25,000 events from this run, which had the configuration "production2009_200Gev_Hi / 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.

 

 

For the following plots, left is South, and up is Down.

Here black is the detector total. North Large=Red, South Large=Green, North Small=Blue, South Small=Yellow
