Table 2.

Fitted values for the tight binding model of Eq. (3) for three different angles as shown in Fig. 5.

$\varphi$	$t_{\parallel }$	$t_{\perp }$	$t_D$	${ϵ}_{0,0}$	${ϵ}_{0,1}$	${ϵ}_{1,0}$	${ϵ}_{1,1}$
10.99	7.024	0.992	0.039	408.359	406.214	407.522	404.923
8.26	2.403	0.094	0.037	369.076	370.521	370.474	371.556
6.61	1.349	0.017	0.036	353.57	355.048	355.249	353.135

Clearly the system becomes more one-dimensional as the angle becomes smaller.

All values are given in meV.
