Evolution of observed CT-AGN fraction from the 100 month Swift-BAT catalogue as a function of redshift (for z < 0.05). The red points represent the CT-AGN fraction within the given redshift bin of 0.01 and blue points show the cumulative value of the fraction within the given redshift. The displayed error bars are in binomial statistics. This figure is updated from the CT-AGN fraction plot of Torres-Albà et al. (2021).
