Average CO spectral line distributions of AGN hosts and star-forming galaxies as well as average SLEDs for AGN hosts and star-forming galaxies normalized to the average CO (2 − 1) flux of main-sequence galaxies at z ∼ 1.2 from V20a. Filled yellow and red circles indicate galaxies in our sample with f_AGN ≤ 20% and > 20%, respectively. Open yellow and red circles show objects split according to their Chandra detection at 2−10 keV. Blue open squares represent the SLEDs of the main sequence and (extreme) starbursts (> 7×) > 3.5× above the main sequence from V20a. Filled light and empty dark green stars show the average SLEDs from the stacking in Kirkpatrick et al. (2019), splitting AGN hosts and star-forming at f_{AGN,  mid-IR} = 50% (comparable with our f_AGN = 20% threshold; see their Eq. (1)). The dashed gray line marks the QSO SLED in Carilli & Walter (2013). The L′ luminosity values for our samples are reported in Table B.1. We note that the statistics of X-ray detections of AGN with measurements of CO (4 − 3) are not sufficient to derive an average estimate.
