This is a close triple system discovered with AstraLux, where in |
|
|
particular the tertiary component is difficult to fit for. Since the |
|
|
relative positions of the BC pair components are therefore clearly |
|
|
dominated by noise scatter in both separation and position angle, we |
|
|
set the error of each epoch to the scatter among the data points and |
|
|
make no assessment of orbital motion for the BC pair (although by |
|
|
contrast, clear orbital motion is seen of the pair with respect to the |
|
|
A component). |
