Plotted the REFL_A_9_I and REFL_B_9_I analog outputs.  Units are uncalibrated RF9 I monitor Volts/rtHz.
REFL_A is still being used for CARM control, REFL_B is just an out of loop sensor.
For reference, here's the last calibrated CARM noisebudget I made.

Looks like sensing noise dominates at 1kHz and below, and the seismic/scatter noise rises much faster below 10 Hz.  What could this excess low frequency noise imposed on the laser mean for the rest of our control loops?

According to the digital LF readouts, there's 5.2 mW on REFL A, and 4.8 mW on REFL B at the time of these measurements.
