Statistics of unfiltered and medium-filtered perturbed and ideal voids that overlap more than 50% for different merging thresholds.

Unfiltered (R_p, i min = 6.3/6.5 Mpc h⁻¹)	0	53	6.6	20.7	12.9	7.4	23.3	13.2

Notes. Columns show the filter type, together with the minimum void radius, R_min; merging threshold, ρ_threshold; the number of voids that overlap in volume with more than 50%, N_voids (> 50%); the occupied volume in the box, V_box (%); and maximum and mean void radii, R_max, $\bar{R}$ $\bar{R}$ . The subscripts for the parameters in these columns indicate whether it’s a recovered perturbed void (p) or an ideal void (i).
