The SSFR − M _⋆  relation for the total sample. Green dots and yellow dots represent objects for which f_ySP are larger or lower than 10%, respectively. AGN contaminated objects are represented by red stars. The black dashed line shows the detection limit. We overplot analytical models of Buat et al. (2008) (dash-dotted yellow line) at z = 0.7 and Noeske et al. (2007a) (connected blue crosses) at z ~ 0.7, and observations of Elbaz et al. (2007) (solid black line, z = 1) and Santini et al. (2009) at z ~ 0.7 (dashed green line).
