BU 139 | AB: This object was misidentified as HD 179558 by McAlister et al. | McA1983 |
V338 Sge, Algol-type eclipsing binary, P = 3.49784 d. | Zas2011 | |
STTA177 | AC: Optical pair, based on study of relative motion of the components | |
using the method of apparent motion parameters. | Kiy2008 | |
BU 139 | AD/AE: Confusion in component designation, with the "D" component of | |
the 29" AD pair not the same star as the "D" component of the 137" CD | ||
pair. The ADS identifies the two pairs as "Aa" and "CD", respectively. | A__1932a | |
The IDS changes "Aa" to "AP" (due to the lack of lower-case letters | IDS1963 | |
available on the IDS's computer punch cards). However, some measures | ||
of the pair are also listed erroneously as an additional pair in this | ||
system, identified as "AD". The two pairs were later recognized as | ||
being the same, and were merged under the "AD" designation in the WDS. | ||
The designation for 29" pair has been changed to "AE". Our thanks to | ||
Steve Smith (2014, private comm.) for pointing out the discrepancy. |
