STT 231 Mt. Wilson spectral types M1, M2, G5.
AB: NLTT 26534/26531 Chm2004
Pair was listed, but in a "rejected" list, not part of discoverer's
regular numbering sequence.
AB Hyperbolic orbit by Hopmann (1960). e = 575. Hop1960b
sigma = areal constant in the true orbit = 3.75 arcsec^2/yr
q = periastron distance in the true orbit = 33".73
All hyperbolic orbits rejected from Fourth Orbit Catalog Wor1983
AC: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
