**Figure 1.**$\mathrm{Im}{D}_{1}$ (vertical) versus X (horizontal). For $\left|X\right|\le \sqrt{5+3\sqrt{3}}$ (with $b=1$), the imaginary part of ${D}_{1}$ is zero, so the solution is valid in this region.

**Figure 2.**The scalar potential (vertical) versus X (horizontal). The dashed red lines mark the values $X\approx 2.02$ and $X\approx 3.04$, while the solid red line stands at $X\approx 3.19$, the upper limit on X.
