For Livingston: No large glitches. Glitchaverage failed with rate of 0.032Hz. For Handford: it is not in observing or low noise mode. Excess noise at 100-1000Hz 1.5 s before and after the merger time periodically from Omega scan. Stationarity and Rayleigh failed. The template length is ~17 s from GraceDB..- Selected
