Azimuthally averaged emission properties for CO isotopologs and CN. Top row: column density profiles for each analyzed tracer. Shown together in the leftmost panel are ¹³CO and C¹⁸O. Middle and right panels: column density profile of each CN hyperfine group, separated between north and south sides of the disk. Bottom row: Optical depth profile for each molecule, following the same order as the top row. The horizontal black lines indicate the optical depth of τ = 1. In all panels, the shaded regions show the uncertainty on the model.
