Slides 5-November-2003

Bob looked at the BSU timings with higher statistics, and also looked at the rates. In both West and East we see a curious pattern to the phi distribution. The great dip in the middle seems clear enough--there aren't any CMX chambers there, and this sample is dominated by CMX triggers. I don't understand the slow droop towards the middle of the plot. I guess that the spikes show where the rather complex geometry of the CMX has greater acceptance in the region that overlaps the BMU. I hope that this isn't reflected in the CMX in general, and is merely a fence-post effect at the end of their chambers.
