Same as Fig. 1, but now adapted for the ejecta properties of model r0e2 (M_ej = 9.69 M_⊙ and E_kin = 4.12 × 10⁵¹ erg). Over-plotted are the results for models r0e2, r0e2ea, r0e2eb, and r0e2ec, which differ primarily in the initial magnetar spin period. The initial magnetar properties for the models are B_pm = 3.5 × 10¹⁴ G and P_pm = 7.0 ms (r0e2), B_pm = 3.5 × 10¹⁴ G and P_pm = 5.0 ms (r0e2ea), B_pm = 3.5 × 10¹⁴ G and P_pm = 4.1 ms (r0e2eb), B_pm = 2.0 × 10¹⁴ G and P_pm = 2.0 ms (r0e2ec). The value of the rise time is affected by the prescribed deposition profile (see Sect. 4) and probably by the neglect of dynamical effects as well (more problematic in more energetic explosions; but see Appendix A).
