No companion is seen on Aladin at Luyten's original theta value. It |
Luy1975 |
|
appears likely that his theta value was due to a trigonometry error, |
|
|
however, and that the correct value was 270-28 = 242deg rather than |
|
|
270+28 = 298deg. A star seen at that position angle and Luyten's |
|
|
separation agrees with his magnitude and has a proper motion in |
|
|
reasonable agreement, as well. Theta has been changed accordingly. |
