Same as Fig. 3 but for the three-sine-wave initial conditions, from left to right, Q1D-3SIN [ϵ_3D = (1/6,1/8)], ANI-3SIN [ϵ_3D = (3/4,1/2)], and SYM-3SIN [ϵ_3D = (1,1)], respectively. We note that in SYM-3SIN, the closest snapshot from collapse we had at our disposal from our Vlasov runs, â_sc = 0.03190, is significantly beyond the actual shell-crossing time estimated by the method described in Sect. B.2, a_sc = 0.03155, which explains some discrepancies between the theory and the simulation at small radii.
