Fig. 2 (Color online) Wigner function $\mathcal{W}_{s,a}$ for the state $\left \vert \xi \right \rangle_{s,a}$ of Re $\alpha$ and Re $\beta$ for different values of $(q,m,n,\varsigma)$, where $(2,0,0,0.1),(5,0,0,0.1),(5,0,0,0.6),(5,2,0,0.1),(5,3,0,0.1),(5,0,2,0.1),(5,0,3,0.1),(5,3,3,0.1)$ respectively refer to (a), (b), (c), (d), (e), (f), (g), (h).
