Since we are not using some of our violin mode BLRMS monitors, I coopted six of them to make BLRMS of the DARM error signal from 60 to 180 Hz, with notches for the 60 Hz and 120 Hz mains lines. The channels are as follows:

• H1:SUS-ETMX_L2_DAMP_MODE6_BL: 60 to 80 Hz
• H1:SUS-ETMX_L2_DAMP_MODE7_BL: 80 to 100 Hz
• H1:SUS-ETMX_L2_DAMP_MODE8_BL: 100 to 120 Hz
• H1:SUS-ETMX_L2_DAMP_MODE9_BL: 120 to 140 Hz
• H1:SUS-ETMX_L2_DAMP_MODE10_BL: 140 to 160 Hz
• H1:SUS-ETMX_L2_DAMP_MODE5_BL: 160 to 180 Hz

In the longer term, we might consider adding new BLRMS to OAF which are expressly for this purpose.
