(a) The two-dimensional plot for of (1). (b) The line in (a) gives a one-dimensional plot of by two-dimensional interpolation. (c) A one-dimensional cross-sectional plot of , when . (d) The maximum and minimum widths of spiral pulses as a function of the parameter of (1). The values of on the -axis are 1.06, 1.05, 1.045, 1.04, 1.038, 1.037, 1.035, 1.032, 1.03, and 1.025 (from left to right).
