Hello,
I would like to ask, if somebody knows anything about comparison post-Newtonian approximation of gravitational waves and these which were detected. Or generally post-Newtonian predictions vs. facts found in detection. I tried find some article but I didn't find. Please let me know what you know or refer me, please.

Thank you everyone.

I think there's some discussion of the PPN approximation for gravitational waves in Misner, Thorne, Wheeler, "Gravitation". I think I recall some fine points about PPN and insprials, something about PPN being good enough if the orbit didn't decay, but not quite good enough when it did. I don't have time to look it up at the moment though.
