BU 1442 LDS 960. Proper motion of A = +792,-1114; PM of B = +794,-1119 (UCAC2)
AB: SHY 73. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
Epoch-2000 coordinates of F = 1425269+233745, current AF separation
~3'.9 at 280deg. Proper motion of C -005+000.
AC and AF: Optical pairs, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
AD and AF are the same pair, so were merged. Abetti (1922) was Abt1922
apparently confused, due to the very large proper motion of A.
