Ratio of completeness-corrected found and expected number of galaxies in our VLT/VIMOS survey within 1000 km s⁻¹ from the redshift of the BLAs, as a function of the maximum impact parameter used to define the area of the cosmic volume subtended by VLT/VIMOS, from 100 kpc to 3.2 Mpc. Each line is colored by the redshift of the BLA, as indicated in the top-right part of the panel. Note that for the BLAs at low redshift (blue and orange lines), we can only probe impact parameters up to ∼500 kpc.
