CHR 86 |
Aa,Ab: This system, first announced by McAlister and recalled in a |
McA1984b |
|
later McAlister paper after repeated attempts at confirmation, has |
McA1993 |
|
been restored. While perhaps still spurious, the subsequent |
|
|
confirmation or suspected duplicity (by another technique) makes the |
|
|
discovery measurement somewhat more probable. |
|
STT 589 |
AB: Optical pair, based on study of relative motion of the components |
|
|
using the method of apparent motion parameters. |
