I am curious why the target = 0 have a wave like pattern. Shouldn't it be more like white noise?

Hi,
\nJust to be clear, the target=0 data do not contain any gravitational waves (GW). A single GW contains an inspiral phase (the black hoes orbiting each other), a merger phase (the black holes forming a single black hole), and a ring-down phase (the single perturbed black hole having a decaying oscillation). This is the classic compact binary coalescence signal shown in the image on the Overview page. What you are showing in your attached plots is just the low frequency noise from the detector - not to be confused for a signal. I hope this helps.

Okay, but can it be this way? 0= Inspiral and 1=Merger? screenshot

\nMy sense is that as their are systematic sources of noise, they probably cause strain to behave in a periodic way. The way data is generated is by modeling this noise and that might be leading to wave like pattern even when target = 0.
