The (a, b) row directly reproduces experimental phase diagram data on the 13 × 13 lattice (data extracted from ref. 18 Fig. 4), while the (c–e) row is 13 × 13 numerical data computed in this work. The first two columns show the order parameters used in ref. 18 to identify the square/striated and star phases, while the third column shows a new, more sensitive order parameter for the star phase. Red dots in (a)-(b) denote the phase boundaries assigned in ref. 18, while the cyan dotted lines in (c–e) indicate the subset of parameter space that was computed. Our calculations support a re-interpretation of the experimental data with a significantly larger square/striated region and much smaller star phase.
