Ignore the "KEK November 2007" title - that's a legacy and is already changed :-)
As of now, there is no distinction in 16 separate zones. However, the gaps between the the zones are clearly visible in the Hit Profile, as the edge strips on both sides have a larger sensitive area and thus collect more hits than other strips; hence the spikes in the (otherwise pretty gaussian) beam profile. There is a single strip with no entries in the center - that's the one that suffered from the bias bond repair action.
SNR=21 (peak mode) is pretty healthy and fits to similar detectors operated with APV25.
All data was taken in multi-peak mode with subsequent hit fitting to obtain amplitude and timing (see separate posting for timing precision).
The verbose output of the analysis is pasted below.
