(a)-(c) correspond to the cases in Figs. \[fig6\](a)-6(c), respectively. The left (right) panels in (b) and (c) are for a fixed ratio of $U_{\textrm{M}}=U_{\textrm{L}}$ ($U_{\textrm{M}}=2U_{\textrm{L}}$). $q_\textrm{mag}[\textrm{M}\sigma]$ denotes the magnetic ordering vector for M$\sigma$ sites that changes at the parameters indicated by the broken lines. ($q_\textrm{mag}[\textrm{L}]$ is always $(\pi,0,0)$, as shown in Fig. \[fig6\](d).) ](fig7.eps){width="8.4cm"}

----------------

In Fig. \[fig6\], we show ground-state phase diagrams for three different parameter sets corresponding to \[Au(tmdt)$_2$\]. Figures \[fig6\](a) and \[fig6\](b) are those with fitted results for the room-$T$ and low-$T$ structures, respectively, in Table \[table1\]. Besides them, to see the effect of the reduction in $\Delta_{\textrm{M}\sigma}^0$ more explicitly, we artificially decrease it from its room-$T$ value as $\Delta_{\textrm{M}\sigma}^0 \rightarrow \Delta_{\textrm{M}\sigma}^0-0.1$ eV, while leaving the other room-$T$ parameters unchanged: This is shown in Fig. \[fig6\](c). The distinct states are indicated in the phase diagrams by different symbols summarized in Fig. \[fig6\](d), together with their magnetic ordering vectors. As can be seen there, the AF order on the L sites always has the pattern
