Comparison of the number of voids present in the WISE-PS1 and WebSky mock catalogs in the north (left) and south (right) regions. The difference in the coverage areas of the northern and southern masks accounts for the variation in the number of voids observed. Furthermore, there is a 13% difference in the overall number of voids between the LRG catalogs, with 6090 voids in the WISE-PS1 catalog and 6992 voids in the WebSky mock catalog. We used the filter definition R_v >  20 h⁻¹ Mpc, δ_c <  −0.3 and δ <  −0.05, following Sánchez et al. (2017).
