| A 2189 | Systemic mass is estimated at 4.1 +/- 0.5 Msun, assuming a dynamical | |
| parallax of 4.75 +/- 0.15 mas. The Hipparcos parallax for this pair | ||
| is poorly determined (3.67 +/- 1.12 mas) | Doc2008a | |
| Malkov et al. (2012) derive dynamical, photometric, and spectroscopic | ||
| masses of 27.45 +/- 27.60, 6.25, and 2.09 Msun, respectively. | Mlk2012 |
