The timing of the data gives us the total mass. about 60sun

(The frequency is inversely proportional to the mass)

The detailed shape of the waveform gives relative masses

spins of the black holes (weakly)

The amplitude gives us the distance to the system.

(h=.1 at about 10 times the Schwartzschild radius)

about 1.2

About 1billion light years away.

The difference in shape and amplitude of the curves give

refined direction and orbital parameters

(No difference between the curves at the two)

The time delay (.007 sec) give part of direction in sky.
