Expert classification vote fractions for the GZ-selected, non-GZ control, known RPS, and GZ-field galaxy samples. Top: Fraction of votes considering a galaxy to be affected by RPS. Based on expert classifications, a low number of both the GZ-selected and non-GZ controls have clear RPS features. Bottom: Fraction of votes for RPS, both RPS and tidal features, or features of undetermined origin. The known RPS galaxies have a higher fraction of objects that are considered to have RPS features when considering the three categories, compared to only RPS (see top panel). Using this metric, the GZ-selected sample (green) contains more galaxies with a high fraction of RPS votes, compared with the non-GZ controls (orange), or the GZ-field (cyan). All counts are normalised such that the area under each curve is equal to one.
