b and log N_HI extracted from all the absorption lines. All the lines identified as single lines by our classification model are inputted into regression model 1, and all the lines identified as double lines by our classification model are inputted into regression model 2. The output from both of these models is plotted as the green line in comparison to the b and log N_HI estimates by D16 (purple) and VIPER (red) extracted from their single and double identified lines.
