YLW 11	AB: IR sources in rho Oph cloud. WL 20.
	WL 20E, WL 20W, and WL 20S are the A, B, and C components,
RES 1	respectively. Astrometry based on average of data taken through three
RIE 1	BC: filters: 7900+/-760, 10300+/-1010, 12500+/-1160nm. See Ressler et	Res2001
	al. (2001) for fluxes of all components at various wavelengths, as
	well as extensive discussion of system. Duplicity of WL 20 was
	discovered by Rieke et al (1989), although no astrometric measurements	Rie1989
	are listed in their paper.
