Relation between the velocity dispersion σ (left) and SFR density Σ_SFR (right) with the residual velocities obtained from the rotation model fitted to the Hα velocity fields. Each point represents a Voronoi region. The top panels show the distribution for the whole sample, while the middle and bottom panels are separated into redshifted and blueshifted residuals, respectively. Square symbols represent median values, with the dashed lines representing 25 and 75 percentiles of the distribution. No clear correlation between the two parameters is observed with v_res.
