Distribution of the misalignment between the photometric and kinematic position angle Ψ_morph−kin for the stellar (left, blue histogram) and the ionized gas (right, red histogram). In each plot line-filled histograms represent the distribution of Ψ_morph−kin for the control sample. Solid lines represent the misalignment which includes 90% of the control sample. Dashed lines represent the same value for the interacting galaxies. The bins located in the gray areas in both components represent the misalignment for those galaxies where is not possible to determine PA_kin.
