Main issue is cluster finding in the large number (~500) of CPS stereo strips in a sector but having time may save the day... New MSU student Qichun Xu, just started –Made a good head-start with an overall algorithms and the cluster finding algorithms in particular Start writing VHDL, expect functional code in about 1-2 months –CPSS (2) : ?! Nobody yet! Perhaps Qichun will take on this one as well...
