CIA 3	Aa1,2: bet Lyr. Eclipsing binary (P=12.9d) resolved by CHARA Array
	(Zhao et al. 2008). Reductions by two techniques (MACIM and BSMEM) and	CIA2008b
	a model fit listed in paper; MACIM and BSMEM results given in WDS and
	Interferometric Catalog. Three possible orbital solutions also given,
	adopting period and Tmin from Ak et al. (2007 A&A 463, 233) and e=0
	(Harmanec 2002 ANac 323, 87). These yield distance estimates ranging
	from 271 to 313 pc; masses for the gainer and donor are 12.76 +/- 0.27
	and 2.83 +/- 0.18 Msun, respectively.
	Aa1,2: Malkov et al. (2012) derive dynamical and spectroscopic masses
	19.84 +/- 11.13 and 15.84 Msun, respectively.	Mlk2012
	In addition to the close pair there is also a hot spot with a size of	IAU2014b
	22-33 solar radii. What is unknown is where the mass is lost and how
	much matter is in the jets.
