Today we added a few filter modules and True RMS parts to the h1oaf model to allow us to monitor the size of the bounce and roll modes in DARM (alog 18706).  One motivation is to allow us to automatically adjust the gains of the damping loops based on the amplitude of the signal in DARM, a second to make it easier to identify which optic is rung up.

The changes to the model were simple;  we use the existing IPC that sends DARM control to the deprecated CAL part of the oaf model.  There are 10 new filter banks, 2 are used for fairly wide bandpasses to include all the bounce or roll modes, the rest are for a specific mode on a specific optic.  I've loaded bandpasses that are 0.04 Hz wide in the single optic filter banks, and I've added gains that make the rms roughly 1 when the modes are damped well enough that they don't show up in the DARM spectrum.  I'll look forward to readjusting these gains when the noise gets better.
