We had a very brief meeting again. Rupesh continues to work on the 
propagation delay calibration under Sean's guidance. He showed fits from 
the macro

one for each of the three regions of the start counter. The quality of 
the fit was hard to judge do to a severely truncated z-axis in the 2D 
histograms. Beni did some digging into the ROOT file, on the fly, and it 
looks like the underlying histograms are OK. This is still work in 
progress.
