Bias–size and bias–maximum surrounding overdensity relations (left, middle), along with the dependence of the bias profile on void type (right), for three different tracer samples with varying minimum stellar mass. The results shown in green correspond to our fiducial void sample, obtained from a galaxy catalog with log₁₀(M_* [h⁻¹ M_⊙]) > 8.33 (same as Figs. 4 and 5). Yellow and blue lines and symbols show the effect of increasing this threshold to log₁₀(M_*[h⁻¹ M_⊙]) > 9.33 and 10.33, respectively. Uncertainties (shaded regions) correspond again to the errors on the means.
