In the $n=1$ case, $X_{s}$ are elliptic curves, and the toric charts cover the entire $X_{s}$. In the $n=2$ case, $X_{s}$ are quartic K3 surfaces, and the toric charts cover most parts of $X_{s}$ including a large portion of the intersection of $X_{s}$ with the toric boundary of $\mathbb{P}^{3}$, but do not cover a tiny neighbourhood of the 24 points located at the intersection of $X_{s}$ with $\{Z_{i}=Z_{j}=0\}$.
