I add a question about the effect of GW on human body..

We can know the the evolution of the orbital period from Figure1 directly, but there are only several orbital periods. The redshit, black hole separation and mass parameters are not coupled?

The power spectrum of Figure1 is redshifted, right? "There are no other ways to measure their mass more accurately." You mean the masses derived are rough or not? Figure1 only covers several orbit periods. For ground based dynamical mass measurements, dozens of radial velocity points are needed at least.

I know how to calculate it now. Thank you.

What does this interation mean? Why do we integrate like this? You can not say E is $mc^2$ and that is all. We can not derive $Ne$ in a light curve directly. How to derive it then? I have specified my question clearly before your answer, right?
