Main plot: comparison between SFR_{IR + UV} and SFR_UV0 corrected using the A_IRX vs. β relations derived in the paper. β is derived from spectroscopy, when possible, otherwise from photometry (see the text for more details). Upper plot: black empty histogram is the distribution of SFR_UV0 over the entire sample of SFGs; black filled histogram is the distribution of SFR_UV0 over the sample of 24 μm-detected sources (both with and without PACS data); red empty histogram is the distribution of PACS-detected sources only.
