BU 702	A: del Cep = 27 Cep. Prototype of the Cepheid variables, P = 5.36d.
	A: Gallene et al. (2016) searched for close companions to del Cep,
	using the CHARA Array. H-band magnitude limits for separation regimes
	r < 25 mas, 25 < r < 50 mas, and 50 < r < 100 mas of 6.17, 5.63, and
	5.26 mags correspond to spectral type limits for possible companions
	of F0V, A1V, and B9V, respectively,	CIA2016a
	NPOI Limb-darkened diameter 1.52 +/- 0.02 mas,	NOI1999
	R = 51. +/- 9. \rsun.
	NPOI Limb-darkened diameter 1.520 +/- 0.014 mas.	NOI2001a
STFA 58	STTA235. C is variable and a spectroscopic binary.
	AC: H 5 4.	MEv2010
	C: Benedict et al. (2002) used the HST FGS3 to derive parallaxes for
	del Cep (3.66 +/- 0.15 mas) and its 40" companion HD 213307 = STFA 58C
	(3.65 +/- 0.15 mas). Residuals to the data for the C component showed
	long-term and non-linear trends, which they used to derive a
	preliminary perturbation orbit with period 390d and a = 2.0 mas.	AST2002b
	In addition to detecting the unresolved spectroscopic companion with
	P = 2202 +/- 6d a parallax of 4.09 +/- 0.16 is determined for the
	system from Hipparcos Intermediate Data.	IRA2015
	Masses are 5.2 and 4. Msun. Estimated period = 345,000y,
	a = 10,000au = 38.6".	Evs2013
