Left: B-band Tully–Fisher offsets compared to the asymmetry index values. Right: stellar-mass (M_*) Tully–Fisher offsets compared to the asymmetry index values. In both diagrams the orange and white stars represent regular and affected cluster objects, respectively, while the blue and white circles represent regular and affected field galaxies. The orange and blue dots joined by lines of the same color show the mean values and standard deviation of our cluster and field sample divided into four bins according to their asymmetry index (A ≤ 12.5, 12.5 ≤ A ≤ 25, 25 ≤ A ≤ 37.5, and 37.5 ≤ A ≤ 50). The vertical dashed black line at A = 25 shows the limit between the kinematically regular and affected categories.
