Upper panels: fraction of SFN (left panel), optical AGN (middle panel), and passive galaxies (right panel) with respect to stellar mass. The fraction in SIG (N_T = 2299) and SIP (N_T = 764) galaxies is depicted by red circles and green squares, respectively. For the control samples, blue triangles correspond to the fraction in SDSS pairs (N_T = 2251) and magenta stars for SDSS single galaxies (N_T = 6867). The number of galaxies in each stellar mass bin is shown in tables for each sample at the bottom of each panel. Error bars are given by considering binomial distribution. Lower panels: fraction of each AGN subtype with respect to stellar mass for SIG (N_T = 1153) and SDSS single (N_T = 3027) galaxies and central galaxies in SIP (N_T = 387) and SDSS pairs (N_T = 1009). The fractions of LINER (left panel), Seyfert (middle panel), and TO (right panel) galaxies are shown in tables for each sample at the bottom of each panel.
