16 Sgr. A is a spectroscopic binary.
CHR 255
Aa,Ab: Garmany et al. (1980 ApJ 242, 1063) observed a smoothly-varying
velocity indicating that the A component is probably a single-lined
binary with a period of 11 d.
Lindroos (1985) provided the classification of the B component and
Lnd1985
determines a distance of 1.2 kpc.
