Fraction of Lum[OIII] > 10^6.4 L_⊙ as a function of stellar mass, log(M*), for barred AGN galaxies (solid lines) and AGNs in pairs with restrictions in the galaxy pair companion properties defined in the text (dotted and dot-dashed lines). The gray surfaces represent the control sample within uncertainties derived through the bootstrap resampling technique. Each bin for each sample contains a similar number of galaxies. The average number of galaxies in each bin is ≈105 for barred-agn, ≈140 for CS and ≈67 for agn in pairs with restrictions in the properties of the galaxy pair companion.
