Same as Fig. 10; however, this time the |$b\, \mathrm{versus}\, \mathrm{log{(\mathit{N}/ cm^{-2})}}$| plot is shown for saturated profiles at a resolution of |$60\ \mathrm{km\,s^{-1}}$|⁠. The broader range of fitted parameters is an indication of hidden saturation at play, resulting in a larger relative error for the column density estimates (⁠|$\lt ~\delta ^{\mathrm{\log {\mathit{N}}}}\gt = 0.05~$|⁠).
