Same plot as Fig. 3, but for sets 1, 4, and 5. Sets 4 and 5 do not develop convection below ν = 1.34 ⋅ 10⁷ m²/s. Set 4 shows shorter formation times for runs when the scaled shock viscosity is below the value for the reference run and longer formation times for runs with a higher shock viscosity than the reference run. Set 5 shows generally shorter formation times, except for the run with the highest viscosity.
