Notes

  1. 1.

    We absorbed terms independent from the observed s(t) in a redefinition of the threshold.

  2. 2.

    This estimate of f ISCO is strictly valid only when one mass is much smaller than the other, and neglects spin effects.

  3. 3.

    P(s) here play the role of a normalization constant.

  4. 4.

    We will see later that exceptions are possible.
