Outside a black hole, perturbation fields die off in time as 1/tn. For spherical holes n = 2 l + 3 where l is the multipole index. In the nonspherical Kerr spacetime there is no coordinate-independent meaning of ‘multipole’, and a common sense viewpoint is to set l to the lowest radiatiable index, although theoretical studies have led to very different claims. Numerical results, to date, have been controversial. Here we show that expansion for small Kerr spin parameter a leads to very definite numerical results confirming previous theoretical predictions./tn.
