Fig. A.1

Fractional abundance with respect to gas number density of N (top row), N2 (middle row), and HCN (bottom row) as a function of Z/R at R = 10 AU for each disk model. The black dashed lines, purple solid lines, and green solid lines represent results from the fiducial model (including N2 shielding and X-rays), the model with N2 switched off, and the model with X-rays switched off, respectively.
