BLA 4	Aa,Ab: bet Her = 27 Her = Kornephoros. A is a long-period spectroscopic
	binary, resolved by speckle interferometry.
	A measure on 1980.4820 was incorrectly attributed to HR 6148 by
	1975.6273: SB, companion is red.	Bla1977a
	McAlister et al. (1983); it actually belongs to HD 163640.	McA1983
	1983.3043: Only the asymmetry of the ACF peak indicate that the star
	is double. The system has been resolved in the red (Blazit et al.	Bla1977a
	1977) with the 200-inch telescope.	Bag1984a
	Mk III Limb-darkened diameter 3.51 +/- 0.05 mas.	MkT2001
	Mk III Limb-darkened diameter 3.462 +/- 0.035 mas.	MkT2003
	NPOI Limb-darkened diameter 3.53 +/- 0.08 mas.	NOI2001b
	NPOI Limb-darkened diameter 3.472 +/- 0.008 mas, Sp = G5III,	NOI2018
	R = 15.92 +/- 0.40 \rsun, Teff = 5092 +/- 64 K,
	L = 153.7 +/-10.8 \lsun, M = 2.91 +/- 0.11 \msun,
	Age = 0.42 +/- 0.06 Gyr.
	Single line SB; all positive observations have been made in the red
	spectral range (wavelength > 6000 Angstroms) so delta m probably is >3
	in the visible.	Bnu1986
	Hipparcos astrometric solution adopted some elements from the orbit of	HIP1997d
	Plummer (1908).	Plu1908
	P, T, and e adopted from 1908 spectroscopic orbit for Pan et al.	MkT1992e
	(1992) combined solution.
