WDS 13169-3436 I 1567 (HD 115311) : NOTES
 
 
discov_num notes refcode
I 1567 Also known as SEE 171.
Hipparcos parallax 23.18 +/- 1.10 mas. Dynamical parallax 22.7 mas,
masses 0.96 and 0.84 Msun. I 1567 has a well-established orbit by
Heintz (1986) which is corrected here to better match the new speckle Hei1986a
data. Heintz notes that this pair is a "puzzling case" because of some
very discordant historical measures; these deviant points were ignored
in the calculation. Tok2012b
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.20 +/- 0.36, 1.81, and 0.95 Msun, respectively. Mlk2012
