FOX 116 eta And = 38 And. A is a spectroscopic binary, P = 115.7d.
MKT 2 Hummel et al. (1993) orbital elements were derived from Mark III MkT1993b
interferometer astrometry. Combined with spectroscopy by Gordon (1946
ApJ, 103, 13) to yield masses and distance.
Errors are given as "error ellipses"; these values are tabulated
below. Columns include date (BY), major and minor axes of the ellipse
(mas), and ellipse orientation (deg):
