Column density of C2H2 (top row) and HCN (bottom row) as a function of radius for each disk model for the entire vertical extent of the disk (left-hand column) and down to the τ = 1 surface at 14 μm (right-hand column). The solid coloured and hatched regions indicate the range of observed values for the T Tauri (Carr & Najita 2011; Salyk et al. 2011) and M dwarf (Pascucci et al. 2013) disks, respectively.
