Cross-match between AVISM’s voids and those found by DIVE (top panel) and ZOBOV (bottom panel). For all AVISM voids, a point is drawn with the best match found in the other catalogues displaying, first, the colour-coded Dice-Sørensen coefficient for the match and, second, the radius of the corresponding counterpart on the vertical axis. The dashed black line shows the ideal case where the voids matched among the void finders have the same effective radius, whilst the dotted line displays a linear fit to the R − R relation, weighted by the DSC values. The small panels below each main panel show the fraction of voids for each radius that are matched with a DSC above a certain value, given by the different colours displayed in the palette. Redder (bluer) colours indicate higher (lower) DSC, meaning that the matched voids are more similar (different).
