STF2382 A: eps 1 Lyr = 4 Lyr
AB: A premature orbit has been computed.
STFA 37 AB,CD: See ADS for notes of components. A__1932a
AB and CD form the physical quadruple eps Lyrae, separation
208". The observed small RV variations in each pair are probably
merely scatter due to the very poor lines.
BD: SHY 307. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
STF2383 C: eps 2 Lyr = 5 Lyr
CHR 77 Ca: See note for 18323-1439 = CHR 73. Hrt1996b
Ca is an Alpha CVn-type variable.
The measures show a large scatter and there are many observations of
the wider pair without a measure of this close companion. The nature
of the motion or even the reality of this pair is in question. Tok2010b
STF2383 The longitude of periastron in the orbit of CD has been corrected. Gzl1956a
SHJ 277 EF, EG, etc.: A preliminary sketch of the motions of the SHJ group
show the G component may be flying away in position angle ~190 Dal2002a
STF2382 AB: H 2 5. STF2383CD: H 2 6. MEv2010
