and of the less concentrated photon flux given by $\kappa=64$, $\lambda=1$ ([*bottom two plots*]{}). Within both pairs, the first plots show densities of the “right" halves of the fluxes, namely of those starting from the right-hand half of equatorial plane in the figure: the converging (before-the-axis) part $\Phi^2_-$ (\[Phi2-minus\]) is plotted in the right quadrant and the diverging (after-the-axis) part $\Phi^2_+$ (\[Phi2-plus\],\[Fplus\],\[X0Y\]) in the left quadrant; both match along $\theta=0$. The second plots of the pairs show total energy densities $\Phi^2(r,\theta)$, given by superposition $\Phi^2_-+\Phi^2_+$ in all the meridional plane. Notice the different ranges of the plot pairs. Note also that although the colour shading of both pairs of plots is normalized from red (zero density) across the [HUE]{} range to violet-red (largest density), the first-flux maximum is about 0.6, while the second-flux maximum is only about 0.046 (see Fig. \[Phi2-plot\]). Horizontal axis corresponds to the equatorial plane ($\theta=\pi/2$), vertical one to the symmetry axis ($\theta=0$); black hole is down in the middle (small light half-circle).[]{data-label="fluxes-density"}](fluxes-density-colour.eps){width="\columnwidth"}
