Description
During the third Observing run, Fast Scattering was the most
frequent source of transient noise at LIGO Livingston. The noise shows up
as arches in time-frequency plane, usually separated by 0.25 sec (4 Hz) or
0.5 sec (2 Hz) from each other. This noise has been found to be correlated
with elevated levels of ground motion in the anthropogenic and microseismic
band. Depending on the amount of relative motion in these two bands, 2 Hz
or 4 Hz fast scatter shows up. To localize the potential coupling to the
detector, we examined the correlation between ground motion at End and
Corner stations with the noise in DARM.
