Just to follow up our discussions about Compton reconstruction and performance of the CCAL

Below are some occupancy plots for triggered events (trigger bit 1)

Fig. 1 Run 61321 (first Compton production run) 02/26, 1 am
Fig. 2 Run 61331 (middle of production) 02/27, 1 am
Fig. 3 Run 61340 (run recently taken) 02/27, 20 pm 

CCAL Occupancy from DigiHits       (top left)
Energy weighted occupancy from DigiHit   (top right)

The same for Hit factory        (middle plots)
(calibration applied)     

FADC time in the readout window for all CCAL channels  (bottom plot)

The occupancies are relatively uniform (except for a few cells, minor effect)
