Today, during the CAL sweeps (ISC lock state 700) several modes (2, 3, 4, 6, 7, 8, 9 in the 1st harmonic and 12, 13, 14, 16, 17 in the 2nd harmonic) ) on the ETMX were rung up by 2-3 orders of magnitude in the monitor levels. During this time Guardian did not switch-off damping for the rung-up modes and this is due to the settings made last Friday. The rung-up modes rose to their peak amplitude while the CAL sweeps lasted and then Guardian was successfully able to damp each one of them. 

I am attaching ndscope plots for the 1st and 2nd harmonic and the DARM spectrum from 3 different time today (a. before CAL sweeps started - which shows nominal noise floor, b. During CAL sweep: when the modes are rising, c. after CAL sweep when Guardian successfully damps them).
