FA125 chip occupancy
From GlueXWiki
From the first 1000 events in run 11663, 50 um diamond, 1345A solenoid, 80 nA beam. Plotted number of hits in each of the chips per event, channels 0-5 are on one chip, 6-11 are on the next, etc, eg event 21 has only 1 hit on roc25 slot3, and that is for the 2nd chip, so the entry in the histogram for roc25slot3 is 1. The crates are plotted separately so the missing FDC crate contributes only 0s.
