Voids’ size. Panel a: dependence of the HOD measured inside cosmic voids with void sizes R_void. Different line types correspond to different void radius intervals, as indicated in the key. Voids’ type. Panel b: same as panel a, but considering the void dynamical classification, where S-type voids are shown with dotted lines and R-type voids are shown with dashed lines. For both panels, all the uncertainties were calculated by the standard jackknife procedure.
