AB,C triple solution by Soderhjelm (1992), who notes the Hipparcos |
Sod1999 |
|
data are unuseable. Speckle observations needed to strengthen orbit. |
|
| TOK 9 |
CE: As suggested by Tokovinin et al. and after consultation with the |
Tok2005 |
|
author, the measure of Prieto was moved from AB to CE, as AB was |
Pri1997a |
|
unresolved at the time of the observation. This measure of CE predates |
|
|
the discovery by eight years. |
|
|
AC. 1997.0952: In this multiple system, our observation failed to |
|
|
detect the closer pair HU 1399 AB, where the secondary has magnitude |
|
|
9.2 and approximate separation 0".5. |
Hor1997 |
|
Tokovinin (2005) notes that a 1996 measure of the AB pair by Prieto |
Tok2005 |
|
(1997) may actually have been of CE, as AB was unresolvable at this |
Pri1997a |
|
epoch (250deg, 0".09). |
