Data underlying Figure 3. All files are CSV files. <br> For Figs 3(a) and 3(b) each row contains four eigenvalues in columns 2-5 corresponding to a given k-point, with high-symmetry points labelled in column 1. <br> For Fig 3(c) each row contains three numbers, the first giving the distance between the acceptors in the array and the other two giving the expectation values of the z angular momentum on the two atoms in the unit cell. <br> For Fig 3(d) each row corresponds to one arrangement of acceptors on substititutional sites within the (001) growth plane. The format is: Columns 1-3: the integers s_1 to s_3 as defined in the figure; Columns 4-5: the distance d_2 and the opening angle \angle_{22} as defined in the figure; Column 6: the 'gap' between the lowest eigenvalue of the topmost (filled) pair of hole bands and the next (empty) pair - if the value reported is negative, the bands overlap and the structure is metallic; Columns 7-10: the parities \delta_i for the occupied bands at the four time-reversal invariant points in the two-dimensional Brillouin zone; Column 11: the index \nu determining the topological character. For non-magnetic insulating structures, \nu=0 corresponds to a trivial topology and \nu=1 to non-trivial. <br>
