SBS regimes for chain decay example. Evolution in time of (a) stepsize using different initial stepsizes τ(0), and (b) the column of the Romberg table at which the solutions converge sufficiently (this is not necessarily k, as the error level could be accepted at only k−1 or even k+1). SBS parameters are S 1=S 2=0.5,a t o l =r t o l =10−6. For clarity not every point has been given a marker.
