discov_num notes refcode
STF2461 17 Lyr. Mt. Wilson spectral type A is A9n.
A is a spectroscopic binary.
AC: Proper motion of C +1219,+1114. Mt. Wilson spectral type is M3.
Proper motion A : +124+030, E : -004-006, G : -003+007, H : -017-013.
AC: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
KUI 90 Ca: Combined solution from astrometry, spectroscopy, and parallax by
Segransan et al. (2000). Solution yields mass and orbital parallax Sgr2000
determination.
STF2461 AB: H 2 68. MEv2010
