The pair HJ 1867 were improperly precessed before, so observers may |
|
|
have been looking in the wrong patch of sky. Component A of this |
|
|
optical triple has a very high proper motion. The proper motion of |
|
|
component B is quite small. The proper motion of component C is |
|
|
unknown. At some point during the 20th century, the B and C components |
|
|
were in approximately the same position, which probably contributed to |
|
|
the lack of early epoch AC measures. It is possible that some of the |
|
|
early AB measures may have actually been measures of A,BC. A detailed |
|
|
analysis of this system is in Bur2003. AB = G216-044/G216-043. |
|
|
AB: Optical pair, based on study of relative motion of the components |
|
|
using the method of apparent motion parameters. |
