There is infrastructure in the CRS HOQI parts to calculate the power and contrast ration of the HOQI interferometers, outlined in T2400088, but we hadn't engaged the filter banks in the path for those calculations. I've turned the filter banks on, set gains and offsets where appropriate.  There's no MEDM that shows this path, or exposes any channels for checking this, so someone should probably look at that. The calculation is almost missing a factor of 8 for the contrast, that needs to be added in the model. I've added that to the CRS library part, so CRSPROC should be ready for a restart on Tuesday.
