| COU 490 | 1983.3125: Very poor atmospheric conditions. | Bag1984a |
| Systemic mass is estimated at 3.1 +/- 0.5 Msun, assuming a dynamical | ||
| parallax of 6.94 +/- 0.10 mas. Couteau (1999) gives a spectral type of | Cou1999b | |
| F5 for both components. However, 2MASS IR colors suggest a somewhat | ||
| earlier spectral type F0-F2V. Adopting an F2V spectral type yields a | ||
| rough spectroscopic parallax of 6.92 mas, in good agreement with the | ||
| derived dynamical value. | Doc2008a |
