Wu-Yang monopole: numerical calculation

I have been reading the paper by Wu and Yang [1] in which they find the famous Wu-Yang monopole. In the paper there are solutions for three types of monopoles: one has an analytical form, which is the one most often quoted, but there are also two other monopoles with numerical solution only. In this post I use Python/numpy to perform numerical analysis on the latter solution. I use the same notation as in [1].
Wu and Yang obtain the following system of ordinary differential equations $$\begin{align} \frac{d\Phi}{d \xi} &= \psi\label{eq:20170625a}\\ \frac{d\psi}{d \xi} &= \psi + \Phi(\Phi^2-1)\label{eq:20170626a} \end{align}$$ Here $\xi$ is given by $r = e^{\xi}$, with $r$ the distance to the origin. The right-hand side of $\eqref{eq:20170625a}$-$\eqref{eq:20170626a}$ defines the vector field ($d\Phi/d\xi, d\psi/d\xi)$ in the $(\Phi, \psi)$ plane. Its integral curves can be seen in the next figure

The integral curves of the vector field defined by $\eqref{eq:20170625a}$-$\eqref{eq:20170626a}$.
The stationary points are marked in red.

I calculate the integral curve from the point $(\Phi,\psi) = (0,0)$ to $(1,0)$ using the numpy function solve_bvp [2].

The integral curve from the stationary point $(0,0)$ to $(1,0)$ is added in red.

$\Phi(\xi)$ can be seen in the next graph. One sees that $\Phi(\xi) \to 0$ for $\xi \to -\infty$ and $\Phi(\xi) \to 1$ for $\xi \to +\infty$

In the rest of this post I reproduce part of Table 1 in [1].
