It looks like PEM is also doing an injection on BRSX as well as the broader IFO, it's very rung up. I have disabled the damping on it temporarily, we shouldn't use it for a little while. If the damper table runs too hard for too long it can get out of position, which is kind of annoying to fix. I'll check on it tomorrow. For now, the SEI_CONF should be left in WINDY_NO_BRSX. This state is currently using some narrow band sensor correction at ETMX (that bypasses the BRSX) to help with the microseism
