Comparison of star formation rates derived from Hα and Paα observed (blue) and extinction-corrected (yellow) luminosities for LIRGs (circles) and ULIRGs (diamonds). The solid black line represents a one-to-one ratio. The SFR has been corrected using its corresponding A_V correction, i.e. SFR_Hα is corrected using optical measurements of A_V, and SFR_Paα is corrected using the near-IR lines. The Hα luminosities are extracted from García-Marín et al. (2009) and Rodriguez-Zaurín et al. (2011).Uncertainties at 1σ level are represented as black lines.
