Measurements of the logarithm of the ratio SFR/SFR_MS as a function of the logarithm of stellar mass, M_*. The SFRs relative to the MS of star formation for galaxies were computed assuming the average redshift from our QSO2 candidate sample, z = 1.1, and using the relation from Schreiber et al. (2015). The dashed line separates the MS and the SB region at 0.4 dex, as defined by Aird et al. (2019). The blue-shaded area defines the MS region. Each point is colour-coded based on the estimated AGN fraction of CIGALE, frac_AGN.
