STF2272	70 Oph = p Oph. A complicated multiple system with high proper motion,
	which has led to some confusion in component identification. A 1924
	measure by Burton supposedly of AW was not to the same W component as	Btn1929b
	measured in earlier VW observations. The Burton secondary is now named
	Y. Similarly, See supposedly measured the BR pair; this pair is now	See1911
	labelled BZ.
	A component is 70 Oph.
	CHARA Array Limb-darkened diameter of A,B:	CIA2012f
	R = 0.8310 +/- 0.0044, 0.6697 +/- 0.0089 \rsun,
	L = 0.53 +/- 0.02, 0.15 +/- 0.02 \lsun,
	Teff = 5407 +/- 52, 4393 +/- 149 K, M = 0.846, 0.698 \msun.
	Spectral types K0V,K4V. Proper motions of A and B are (+276,-1092) and
	(+442,-1253), respectively. Proper motion of other components follow:
	C : -019-012 D : -002+002 R : -007-007
	S : +005-004 T : +001-006 U : -013-010
	V : +002-014 Y : -023-028 Z : -022+007
	The existence of a third body, for which orbits have been computed, is
	now generally discounted as the strong photographic coverage fails to
	show any such variation. Batten & van Dessel (1976) discuss the radial	Bte1976
	velocities.
	Pourbaix gives combined solution for this resolved SB2, yielding
	orbital parallaxes and component masses.	Pbx2000b

	parallax of 194.2 +/- 1.2 mas. Adopting both asteroseismic and
	non-asteroseismic observational constraints with several models, they
	derive an age of 6.2 +/- 1.0 Gyr, an initial helium mass fraction Y =
	0.266 +/- 0.015, and an initial metallicity (Z/X) = 0.0300 +/- 0.0025.
