Same as Fig. 7, but the Hα luminosity has been corrected from reddening effects. The nuclear E(B − V) values shown in Table 3 have been used for the objects in our sample (see text for details). On the other hand, a 2D reddening correction was applied for the ULIRGS in the García-Marín et al. (2009a) sample. The AGN dominated source IRAS F05189-2524 and all the objects in our sample with unavailable Hα/H_β values are not used for the plot.
