discov_num notes refcode
BAR 41 Identity of this system is uncertain. The Tycho measure supports TYC2002
identification of AB with 155200.97+423948.7. Aitken notes "Star C is A__1932a
BD+43 2537 (8.2, G5)", which supports identification of C with
155156.23+423905.8. However, Barnard gave magnitudes of AB as 15 and Bar1932A
15.5, which appears to agree with an elongated Aladin image at
155209.22+424127.5 rather than the Tycho pair. CA would in this case
be 45.4deg, 200.3", which could be explained by a typographical error
in his value for rho. Unfortunately, Barnard's original publication
for this measure is unknown.
