I've been talking to Jeff about changes to the ISI and seiproc models for SPI and CRS integration. The ISI models are pretty much done, but today I added a parts to seiproc to take HAM2345 cps and gs13 cart channels and blend them to create cartesian differential supersensor channels. The idea being these will be good metrics for determing if SPI is actually improving the differential ISI motion. Plan is to use blend filters to combine the cps and gs13 pairs from each chamber to make supersensor channels, and then compare the differential supersensors  for HAM2-3 to the differential supersensors at HAM45. I've checked that seiproc builds with these changes, but I now have some changes to make to the HAM45 models and some ipcs to make. And then a whole bunch of medm work. 

Erik had to attach my screen shot, because firefox is not cooperating in the control room for me, but it shows a snippet of the flow in the ISI_DIFF block in seiproc and the channels I think Jeff wants to save. We didn't talk about data rate, so that's just a guess.
