Distribution of voids intersecting a thin slice of 400 Mpc/h side length through the centre of the box. Top, middle, and bottom panels show, respectively, results from AVISM, DIVE, and ZOBOV. Different colours are used to show void zones. Voids matching those from the reference catalogue (AVISM in this case) with a DSC coefficient larger (smaller) than 0.4 are displayed using the same colour and continuous (dotted) lines. Voids are shown overlaid on the integrated contrast density field as interpolated by AVISM, represented in a grey colour scale with values displayed in the colour bar below.
