Notes. (a)Identical parameters to pulsed jet simulation of Lee et al. (2001) (see their Fig. 7). (b)Identical parameters to pulsed wind simulation of Lee et al. (2001) (cf. their Fig. 12), except that the wide-angle wind is replaced here by a cylindrical jet of same mass-flux, injection radius, and velocity variability.
