§2.11 Remainder Terms; Stokes Phenomenon
The choice of α and β is facilitated by a knowledge of the relevant Stokes lines; see §2.11(iv) below. … Rays (or curves) on which one contribution in a compound asymptotic expansion achieves maximum dominance over another are called Stokes lines ( θ = π in the present example). … The relevant Stokes lines are ph z = ± π for w 1 ( z ) , and ph z = 0 , 2 π for w 2 ( z ) . … For example, extrapolated values may converge to an accurate value on one side of a Stokes line2.11(iv)), and converge to a quite inaccurate value on the other.
