Left: result from the fiducial grid. The orange, green, and blue points correspond to gd = 10², 10³, and 10⁴, respectively. The black lines highlight a constant C/O ratio. Middle: result obtained for the “enhanced O/H” grid: O/H×10 (C/H is scaled with the C/O ratio). The fiducial grid is overlaid in gray for reference. Right: Results for the disk aspect ratio, h_C (orange), power law index of the dust distribution, q (in blue) with gd = 10³.
