PSI 3	Perci et al. (2005) found [KG2001] 102 to consist of 4 components,	Psi2005
	all within a 2" region. The A component is determined to be
	substellar, with a mass of 33-55 Mjup at a distance of 160 pc. The C
	and D components are believed to be physical companions, but the B
	component, of spectral type K7V, is probably a background star at a
	distance of about 550 pc. Nearby star "Anon1" was also found to be
	double.
