MCT 9 GJ 3928 = G180-011 = LSPM J1555+3512.
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. Jnn2012
