Void counts measured in the redshift-space mock galaxy catalogue considering the redshift bins and selections used for this analysis.
| z range | Shell volume [(h−1 Gpc)3] | MGS [h−1 Mpc] | fcut(z) | All voids | Voids after cleaning |

Notes. The first column represents the minimum and the maximum redshift values for each bin, while the second and the third columns provide the volume in units of (h−1 Gpc)3 corresponding to each shell of the sky octant, and the mean separation between galaxies (MGS), respectively. The fourth column reports the factor, fcut(z), used to select voids unaffected by the incompleteness of counts. The last two columns show the number counts of voids identified by the VIDE void finder with R > fcut(z) MGS and of voids obtained after the cleaning procedure with Reff > fcut(z) MGS, respectively. In the last row we show the total volume of all redshift shells, the mean MGS and fcut(z) values and the total void counts corresponding to the entire range of redshifts. A table with equi-spaced redshift bins is provided in Appendix A to serve as a reference for future forecast analyses needing void numbers.
