STF2580 AC: Rectilinear solution by Friedman et al. (2011). USN2011a
BC: Rectilinear solution by Hurowitz et al. (2014). USN2014b
STF2576 FI: Rectilinear solution by Hurowitz et al. (2014). USN2014b
STF2580 17 Cyg = chi Cyg. LDS1028. B is probably variable.
AB: NLTT 48226/48228 Chm2004
Common proper motion with STF 2576. Moved to same WDS coordinate to
formalize the relationship 7 August 2008 at suggestion of Deepak
Raghavan.
AB: HJL 267. HJL1986
AB: H 4 11. MEv2010
AC: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
KPR 4 AD: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
AD: It is doubtful that the AD pair observed by 2MASS and later
observers is the pair observed by Kamper (1992). Neither his "Af" (AD) Kpr1992
or "Ag" (AE) pairs seems to correspond to any pairs in the field,
when proper motion of the stars is taken into account.
WNO 56 AF is the same as LEP 93. All measures merged into a single system.
GJ 9670 + LTT 15766. CPM pair. Mkr2008
AF: SHY 96. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
STF2576 FG: The longitude of periastron determined by Rabe (1948) has been Rab1948a
reversed to represent the quadrant given by all recent observations.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Aka H N 109 = SHJ 300. Bu_1906
FG: Additional notes may be found in Fatou (1941) and Fat1941
Duruy (1944). Dur1944d
FG: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.55 +/- 0.84, 1.54, and 0.76 Msun, respectively. Mlk2012
TKA 1 FJ. Tel'nyuk-Adamchuk actually observed the FI pair, but due to the TkA1966
high proper motion of F and the long time since the previous FI
measure, his measure was mistakenly assigned to a new component. The
TKA designation has been maintained in order to avoid confusion,
despite the fact that Tel'nyuk-Adamchuk never observed it.
