kap Peg	Double lines have been observed in the spectrum of A.	Tok2006
	The SB1 with P = 5.97 d (#1329 in Batten et al., 1989) is believed to	Bte1989
	to be the visual component B, and a set of double lines is observed
	which is ascribed to star A (Beardsley & King 1976).	Bey1976
	See Baize & Petit (1989) catalog of doubles with variable component.	Baz1989d
	Combined solution by Muterspaugh et al. (2006), using PHASES	Mut2006
	differential astrometry, iodine cell radial velocities, and published
	visual and speckle data. Mass of A is 1.549 +/- 0.050 Msun. Center of
	light motion of Ba,Bb pair is seen, allowing determination of masses
	for both components: 1.662 +/- 0.064 and 0.814 +/- 0.046 Msun.
	Semimajor axis and error in catalog derived from their values of a
	(AU) and parallax, plus errors in those quantities. No sign of
	purported spectroscopic companion to A component. Original tabulated
	data are listed below, including date (MJD), dRA and dDEC (mas),
	errors in dRA and dDEC (microarcsec):

	radial velocity data to derive orbits for both the AB and Ba,Bb pairs
	of this triple. The parallax is determined at 28.93 +/- 0.18 mas
	(distance 34.57 +/- 0.21 pc). Masses of the A, Ba, and Bb components
