discov_num notes refcode
A 1470 1985.8481: Autocorrelogram was remeasured; new results in catalog
Tokovinin gives combined spectroscopic/visual orbit, also yielding
orbital parallax and component masses and absolute magnitudes. Tok1993
Pourbaix gives combined solution for this resolved SB2, yielding Pbx2000b
orbital parallaxes and component masses.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.95 +/- 0.40, 1.85, and 1.26 Msun, respectively. Mlk2012
For the Horch et al. (2015) combined solution, the spectroscopic
elements are fixed to those of Pourbaix (2000). Assigned spectral Pbx2000b
types are G2V and G3V; derived masses 1.00 and 0.97 Msun. Hor2015
