Originally listed as 10442+6111, based on Luyten's 1950 coordinates, |
Luy1970 |
|
but no pair is found at that location. However, a pair in excellent |
|
|
agreement with his measure is found at the location of his cross- |
|
|
reference catalog entry, BD+61 1312. Apparently there was a 2h error |
|
|
in Luyten's 1950 coordinates. Given the size of the error, correction |
|
|
to the WDS designation was deemed appropriate. |
