Maximum velocity of the outflow versus the SFR derived from the infrared (left panels) and reddening corrected Hα (right panels) luminosities. Lines correspond to unweighted fits to all the data (continuous), only objects without AGN evidence (dotted), and only objects with AGN evidence (dashed). The error bars in the SFR(Hα) do not take into account the uncertainties associated to the reddening corrections (see text).
