WDS 13492+0746 LDS 3107 : NOTES
 
 
discov_num notes refcode
LDS3107 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.
