Radial profiles of the density, velocity, and gas temperature of an initial 1 M_⊙ cloud at an initial temperature T₀ of 10 K are shown at the time when central density ρ_c in both simulations reach roughly 10⁻¹ g cm^-3. The bluish purple solid lines show results from simulations described in Sect. 3, while the dashed red line represents results from simulations provided by N. Vaytet (2017, priv. comm.). We note that for this comparison both codes use the same temperature-dependent opacity .
