Table 1
Evolution rates calculated numerically, (drp/ dt)n, and analytically as indicated above, (drp/ dt)a, for different values of the mass ratio q.

| 0.0001 | –2.1e-6 | –2.8e-6 |
| 0.0005 | –1.6e-5 | –1.4e-5 |
| 0.001 | –3.4e-5 | –2.8e-5 |
| 0.003 | –7.9e-5 | –8.3e-5 |
Notes. The evolution rates, time-averaged over several orbits and evaluated at early times, are in units 
, where P0 is the initial orbital period of the perturber. The softening length for these calculations was taken to be 0.6H.
