Void size and redshift distributions for voids in the Pan+12 and the Voids174 samples. Left panel: Relative number of voids as a function of void size (R_void), determined using the effective radius, in units of h⁻¹ Mpc. The green histogram represents the size distribution of voids in the Pan+12 sample (1055 voids) and the cyan histogram represents the size distribution of voids in the Voids174 sample (174 voids). The dashed red vertical line indicates the median value of the effective radius for the Pan+12 sample (17.83 h⁻¹ Mpc). Right panel: Distribution of void galaxies as a function of redshift. The green histogram represents the distribution of void galaxies in the Pan+12 sample (79 947 galaxies) and the cyan histogram represents the distribution of void galaxies in the Voids174 sample (26 864 galaxies).
