Comparison between the measured mean L₆₀ in bins of M_BH and the predictions of two simple alternative models for BLAGN host properties. a) All BLAGNs are assumed to lie in starbursts which have at a mean positive offset of 0.6 dex in SFR from the SF Mass Sequence, or b) the M_BH–M_∗ relation evolves with redshift according to Eq. (2) with δ = 1.0. The measurements are shown as colored points with error bars. AGNs in the 0.5 < z < 1.0, 1.0 < z < 1.5, and 1.5 < z < 2.2 redshift bins are represented by blue, green, and red colors, respectively. The x-axis error bars show the range in the M_BH that encompasses 80% of the sample in the corresponding bin. Neither set of parameters chosen here fit the data as well as the “baseline model” (Sect. 6.1). While model a) performs very poorly in fitting the data, model b) is marginally acceptable, though smaller values of δ are preferred.
