Eddington ratio against covering factor (CF). The solid and dashed gray lines show the trend found by Ricci et al. (2022) and the 1σ uncertainty around it, respectively, when the covering factor of gas is inferred from the fraction of obscured sources using X-ray observations. The solid and dash-dotted black lines show the trends that follow the median CF, derived through IR data, obtained for obscured and unobscured, respectively, sources from the sample of Ricci et al. (2023).
