Relationship between the Hα luminosity corrected for dust attenuation using the 24 μm emission (upper panel), the 20 cm radio continuum luminosity (lower panel), and the Hα luminosity corrected for Balmer decrement using the spectroscopic set of data published in Boselli et al. (2013), where the line emission is directly measured on the data. Filled dots are for HI-normal (HI - def ≤ 0.4) galaxies and empty symbols for HI-deficient (HI - def > 0.4) objects. Black symbols indicate galaxies with an HβEW> 5 Å, red symbols those with HβEW< 5 Å. The black solid line shows the 1:1 relation, the black long dashed line the bisector fit to the high-quality data (black symbols), and the red dotted line the best fit to the whole dataset.
