discov_num notes refcode
HSL 1 Aa,Ab. Masses of 0.887+/-0.030 and 0.788+/-0.021 are determined. Hor2006d
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 2.37 +/- 0.30, 2.12, and 0.95 Msun, respectively. Mlk2012
Aa,Ab: For the Horch et al. (2015) combined solution, spectroscopic
elements are fixed to those of Goldberg et al. (2002 AJ 124, 1132).
Assigned spectral types for Aa, Ab, and Ac are G5V, G8V, and K6V;
derived masses for Aa and Ab are 0.92 and 0.84 Msun. Hor2015
