Variation of ξ in the r − z plane for different magnetisations, μ = 0.0059, 0.0160, 0.0674 (from left to right). The Compton-thick region with N_h > 10^24.18 along the LOS is shown in red. The white line shows the lowest possible Compton-thin LOS and the value of corresponding i value is given next to it. Black solid lines spread over the whole region are the poloidal magnetic field lines anchored at different radii. Density contours are shown in blue dashed lines. The corresponding log of density (in cc) is written just next to each density iso-contour.
