I didn't alog this at the time but the SEIPROC, HAM-ISI and BSC-ISI models were updated this week to allow us to select which ground sensor we want to use, as well as updates to the sensor correction paths. The HAM-ISIs now have code (that the BSCs have had for a while) to smoothly ramp between different sensor correction paths, and a few other changes. We also added a sensing matrix and some extra sensor correction paths to retain the use of cross DOF sensor correction (i.e the Z to X/Y sensor correction like I added on HAM3&4). 

This update also added the ability for all of the ISI's to use the common mode subtracted ground sensor correction paths, that the seismic group has been trying to develop to help with earthquakes. The idea is that  by subtracting the calculated common mode motion of the entire site, we can improve the isolation and reduce drives by only isolating against the local differential ground motion. In the SEICONF guardian, the EARTHQUAKE state is now using that where it's available, although, this code has not been added to HEPI, yet. 

Next week I would like to do one more round of model updates. In SEIPROC, I want to clean up the ground signals to be simpler and reflect the fact that we SEIPROC is written to digest CS BRS (which we don't have, but LLO may want to copy this model, I don't know what they have for an equivalent model). This means there are NORM paths (the normal paths, meant to be a low tilt sensor) and the UNCOR paths, which would be a path that bypasses any BRS as a fall back. This only involves changing PCIE parts from SEIPROC to CS chambers at the top levels of the models and shouldn't affect any control paths. I've done the makes for all the chambers, everyone compiles.
