Left pair: Scwarzschild
Right pair: a/M = 0.998
Upper pair: 10Msun/106Msun, z = 0.1 (0.4 Gpc) -strongest in 1 year with Freitag normal rate
Lower pair: 1 Msub/106 Msun, z = 0.25 (1Gpc) - strongest in 1 year with Bender & Hills rate.
Circular equatorial prograde orbits, m = 2 harmonic, points at 1 year, 1 month, 1 day. See Finn & Thorne (2000) PRD 62, 124021
Height above curve is S/N per octave (except for 1 day point, where explicit sqrt(delf/f) is used).
