Demonstration of how the widths of the a_w method were selected. The color indicates the width of the lobes. Each point shows the best found slope and vertex. In the left panel, there are 4200 points (seven values of the υ_c, 20 iterations of the diameters uncertainty, and 30 lobe widths.) The right panel is a filtered version of the left, only including lobe widths that converge stably to a solution and includes 700 points.
