STF1506 A,BC: Star A (mag 7.64, 11", G5) is physical and in slow direct motion
A 676 BC: Incorrectly listed by Docobo (1984) as STF1514 (erratum noted in Doc1984b
Inf. Circ. 93, 1984)
BC. Eggen's (1967) orbit for this pair of 11th magnitude M dwarfs Egg1967
predicts a separation of 0".20 and a position angle of 86deg at this
epoch. Our measurement is in poor agreement with this prediction. Hrt1992b
BC: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.36 +/- 0.38, 1.19, and 0.91 Msun, respectively. Mlk2012
LAF 43 Heinze et al. (2010) determine the E component is a background object. Hze2010
