Representation of the stellar mass and IR luminosity, both obtained from the CIGALE fits. The circles indicate the objects with z_spec calculated in this work, and the triangles represent the z_sup objects. The median error on both axes is shown in red. The colour code indicates the fraction of AGN we obtained from the SED fits using the IR templates of Dale et al. (2014). The boundary lines on which the LIRG, ULIRG, and HLIRG sources are defined are highlighted.
