| Σdep | 1022 | cm-2 | Surface density for depletion |

| Xu(CO) | 10-4 | CO abundance in upper layers | |
| Xp(CO) | 0 | CO abundance in mid-plane | |
| M disk | 0.7 × 10-3 | M ⊙ | Disk mass |
Notes. Σ(r) corresponds to Eq. (5) in Guilloteau et al. (2011), H(r) = H0(r/ 100 au)− h, and T(r) is defined in Eqs. (1)–(3), this paper. The disk is in Keplerian rotation around a 0.57 M⊙. Only the product of Σ0 × Xu(CO) is constrained by the observations: changing Xu(CO) will change Σ0 and Mdisk by the inverse amount.
