Figure 6. The Husimi function $\mathcal{Q}$ for the asymmetric two atoms (g = 0.5) at $\delta =0$, $\lambda =1$ with $\gamma =x+iy=5$ and $\eta =X+iY$; first row represents $M_1=M_2=0$, second row for $M_1=M_2=60$, third row for $M_1=60$ and $M_2=0$, and the fourth row for $M_1=0$ and $M_2=60$; while the columns represent given moments.
