Continuing on the campaign of gathering open loop gain (and loop suppression & closed loop gain TFs), I measured H1SUSPR2's M1 damping loops this morning -- see

        2025-07-08_1748_H1SUSPR2_M1_WhiteNoise_V_0p02to100Hz_OpenLoopGainTF.xml
        2025-07-08_1748_H1SUSPR2_M1_WhiteNoise_Y_0p02to100Hz_OpenLoopGainTF.xml

SUS was in new HEALTH_CHECK state, but damping loops are *on.*
SEI / HPI / ISI was FULLY_ISOLATED, in its best performing state.

Data analysis and commentary to come.
