Accuracy of retrieved parameters, in comparison to known input value, for the synthetic transmission spectrum generated with the inverse p–T profile, a cloud-top pressure of 1 bar, and the DRS noise case. In all panels, the parameter value is shown in the x-axis, and varying retrieval cases are listed on the y-axis. For each retrieval case, the median retrieved value (black dot), as well as the 1σ uncertainty provided by TauREx (black error bar), and the boundaries of the 3σ-equivalent CCI (grey error bars) are shown. The known true parameter value is indicated with a red dashed line.
