1983.4277: The AB pair is a new component to the 0".7 pair HO 532. |
|
| HO 532 |
This new component was actually first resolved in 1983 (McAlister et |
|
|
al (1987), but it was believed at the time that the measurement was of |
McA1987b |
|
the known pair (the wide component laid outside the processor "window" |
|
|
of our old autocorrelator). Reprocessing of our archival video data |
|
|
allowed us to resolve both components in the 1983 and 1984 data sets, |
|
|
although both early measurements of the AB pair are quite weak. |
