Composition of ice for simulations with different T₀, given at several temperatures (multiples of 10 K) that occur during cooling. Low temperatures are not shown because the ice composition changes little after T_switch. The results for each T₀ are depicted in a pair of plots, with the respective temperatures indicated for only one of the species, but the temperature is also relevant for other species for the given T₀. For clarity, the respective curves for each species are indicated only in every other plot. Water and carbon dioxide are not included because their numbers remain unchanged. The curve marked with the value of T₀ is always the initial ice composition, fully depicted in Fig. 2.
