Nuclear activity estimator as a function of projected distance and normalized distributions for barred AGNs within major and minor pairs compared to control galaxies. Left panel: ⟨Lum[OIII]⟩ as a function of projected distance, r_p, for barred AGN galaxies in major and minor pairs (solid and dashed lines, respectively). The mean value of Lum[OIII] for barred AGN galaxies in the control sample is plotted with a horizontal dotted line. Right panels: Normalized distributions of Lum[OIII] for barred AGN galaxies (solid lines) and BGCP (dot-dashed lines) in major and minor pair systems (upper and lower panels, respectively). Barred AGN galaxies in the control sample are plotted with dotted lines.
