HLD 158 |
Misidentified in IDS as BD+02 4138 rather than +02 4139. Position and |
|
|
proper motion corrected. |
|
|
Pair called "too close" by van den Bos in 7 nights in 1961 and 1962. |
Wor1967b |
|
Confirms comment by Couteau that BD+02 4138 7s s is single. |
Mrl1968a |
|
Meas attributed to ADS 13738 = BD+02 4138 appear to match this pair. |
Mrl1970d |
|
This is BD+02 4139, observed my Morel (1968). Coordinates are those |
|
|
given by Aitken for ADS 13738 = HLD 158 = BD+02 4138 -7s, which was |
|
|
found to be single. Probably ADS 13738 = BD+02 4139. |
