Source region shapes.

Several region shapes can be selected through parameter shape: circle, box, diamond, ellipse and boxcircle. The size of these regions is determined once the radii is calculated as explained in previous section:

• - box side = $2 \times$ circle_radius
• - ellipse_minor_axis= circle_radius
• - ellipse_major_axis= $2 \times$ circle_radius
