For simulations where σ ang ≥ 0.2, looking at the low temperature RDFs, we found four distinct phases which changed as a function of increasing σ ang (Fig. ). We chose the three most disparate phases (in terms of their RDF, Fig. )) which became the red, green, and blue components of our phase diagram, Fig. . As with the window-to-window simulations, this phase diagram loses some information as we exclude the orientational behaviour of our structure due to the RDF data containing only the central positions of the cages. Nevertheless, it is a useful way to highlight different phase behaviour and as expected, the phase behaviour at low temperatures of our phase diagram evidences the four different phases seen in the RDFs, shown through the different coloured sections at σ ang = 0.2 -0.4, 0.5, 0.6,and 0.7 -1.0, Fig. (a). To ensure we were not missing any other phases due to the discrete values of σ ang chosen, we ran simulations at intermediate values between σ ang = 0.4 -0.7 where the majority of the different phase behaviour lies, but this did not result in any new phases.
