It all boils down to what they subtract. It is said that they subtract the wave signal. Is this signal known for sure or very predictable ? It also depends on how they subtract it.
Is it in the fequency domain or the space doman ? I didn't read the arXiv article and don't plan too. Just commenting and asking.
- yodon 9y agoThink of it as a matched filter tuned to the impulse response of a gravity wave. If that filter matches the observed signal then it's a detection, if it doesn't then it's not. The debate is over the significance of the inevitable remainder after subtracting the model of the signal. Is it an expected amount of remainder or an unexpectedly large amount of remainder.
