| Linewidth | 3.2 ± 3.2 km s-1 | |

| χ2 | 3.96 | |
Notes. 1) Based on an early B type primary and an F type companion (M2003); 2) this sets the minimum possible inner disc radius, based on the values reported by M2003; 3) set by our previous AMBER observations (W12) and assuming that the CO emission is co-planar with the continuum emission. The outer radius is simply the radius at which the temperature falls below 1000 K, and in this case is approximately 6 AU.
