Daemgen et al. (2007) derive a distance of 12.6 +/- 3.6 pc, separation |
Dae2007 |
|
of 19.8 +/- 5.7 au, and predicted orbital period of 216 +101/-97 yr. |
|
|
Spectral types are M4.0 +/- 0.5 and M7.0 +/- 2.0; masses are 0.20 |
|
|
+0.09/-0.06 and 0.08 +0.06/-0.03 Msun. |
|
|
Law et al (2008) derive a distance of 10.2 +5.6/-1.7 pc and a |
Law2008 |
|
projected separation of 15.7 +8.8/-2.5 au. Estimated spectral types |
|
|
are M4.5 and M6.5. |
|
|
In addition to the astrometric points listed in Table 4, there is |
|
|
another data point from 2005 in Law et al. (2008). This point is |
Law2008 |
|
essentially at equal epoch to the Daemgen et al. (2007) point, but the |
Dae2007 |
|
position angle differs by 88deg in the two cases. While the Daemgen et |
|
|
al. data point is fully consistent with all other astrometric points |
|
|
of the target, the Law et al. point is fully inconsistent in this |
|
|
regard. The close to 90deg offset could imply some trivial |
|
|
trigonometric error in reduction. Here we simply exclude the point |
|
|
from our analysis. |
