$^a$ Integrated H$\alpha$ observed flux, with units $\times$10$^{-14}$~erg~s$^{-1}$~cm$^{-2}$. Note that in the cases of IRAS~13156+0435 and Arp~299 we derived the integrated flux for each galaxy of the interacting pair   using their individual pointings; $^b$~ratio between the H$\alpha$ nuclear, identified as the peak position in the optical continuum and total observed fluxes; $^c$~observed H$\alpha$ luminosity derived from the integrated flux in Col.~2. Units in $\times$10$^{41}$~erg~s$^{-1}$; $^d$~integrated two-dimensional extinction corrected H$\alpha$ luminosity, with units in $\times$10$^{41}$~erg~s$^{-1}$; $^e$~integrated H$\alpha$ extinction-corrected luminosity, derived using the total observed flux and the median extinction, with units in $\times$10$^{41}$~erg~s$^{-1}$; $^f$~observed nuclear H$\alpha$ luminosity with units in $\times$10$^{41}$~erg~s$^{-1}$; $^g$~extinction corrected nuclear H$\alpha$ luminosity, derived using the nuclear extinction of each individual galaxy. Units in $\times$10$^{41}$~erg~s$^{-1}$; $^h$~for this particular galaxy we have calculated the ratio using the position of the true nucleus of the galaxy, which does not coincide with the optical one (Garc\'{\i}a-Mar\'{\i}n et~al. \cite{Garcia2006}); $^i$~the data for Mrk~273 do not have an absolute flux calibration. Hence, only the relative measurement between the nuclear and integrated H$\alpha$ flux is given here; $^j$~as shown in Fig.~1b, the area of this galaxy with available extinction values is limited, also presenting a very large peak value. The use of this value for correcting the integrated flux is not valid and therefore is not included in the table.
