Normalized SFR – M_⋆ diagrams before constraining the extinction from the IRX ratio (left), and after (right). The top panels are colored by SFH, while the bottom ones are colored by redshift. For each source, only the preferred SFH is plotted (diamonds for declining, triangles for rising, squares for delayed, and circles for CSFR models). When the extinction is a free parameter we see that many of the sources are best fitted with models of reduced star formation, and hence can be quite below the MS (marked here by the solid black line, while the dashed lines show the distance 4 times from it).
