STF2758	61 Cyg. According to R.G. Aitken, this was discovered in 1753 by	A__1935f
	Bradley. Premature orbits have been computed for AB. This is an	Bdy1832A
	example of a binary known by its common parallax and proper motion
	rather than the orbital motion, which has completed approximately
	one-sixth of an orbit in the past 200 years. The extremely large
	proper motion of this pair has led to some confusion in identification
	of others stars measured relative to the primary. Precise epoch-2000
	coordinates and UCAC2 catalog cross-identifications are listed below:
	A = UCAC2 50084730 = 2106539+384457 pm = +5328 +3258
	B = UCAC2 50084732 = 2106552+384431 pm = +5267 +3143
	C = UCAC2 45407969 = 2106142+383502 +007+006
	D = UCAC2 45407870 = 2105597+384133 +002-006
	E = UCAC2 45408060 = 2106306+384532 +012-007
	F = UCAC2 45408067 = 2106322+384246 +019-002
	G = UCAC2 45408111 = 2106413+384325 +000-002
	H = UCAC2 45408157 = 2106502+384551 -004-006
	The Aa pair was renamed AF. The G and H components were both initially
	believed to be the C component. B is BD+38@4344.
	AB: Statistically the same parallax within the errors would indicate
	the components are physical.
	AB: H 4 18.	MEv2010
	An estimated mass has been used by Josties (1981) to compute the	Jti1981
	otherwise nearly indeterminate orbit; thus the orbit should not be
	used to compute the mass. The RV difference from which the ascending
	node is inferred is quite small. Various small variations, formerly
	suspected in the period range of about 5-10 years, are absent in the
	strong photographic coverage of the last decades.
