                       10.26 +/- 2.92 mas from van Leeuwen (2007). A previous orbit was        VlF2007 
                       calculated by Cvetkovic (2008) with period of 109 years and semimajor   Cve2008c
                       axis of 0.344 arcsec. However, our new observation shows that the               
                       system has a much shorter period and smaller semimajor axis. However,           
                       our orbit yields roughly the same total mass, with large uncertainty.           
                       The system appears to have executed nearly a full orbit since the               
                       first speckle observations taken of it in 1985 by McAlister et al.              
                       (1987). More data will be needed to confirm this orbital trajectory,            
                       but if correct, the smaller period makes the system much more                   
                       attractive for future study.                                            Hor2015b

                       the SW at a milar distance is 2MASS J02480263-2835465. There are no

02490-1029 BRG  16     The system is precisely at the 3 sigma threshold for statistically              
                       significant exclusion of the background star hypothesis. By chance,             
                       the AB astrometry is just below the criterion (2.7 sigma) and BC is             
                       just above (3.1 sigma), so in principle the BC pair is inconsistent             
                       with chance alignment, if the pair does share a common proper motion            
                       with  A. However, the proper motion of the system has of course been            
                       determined based on A, so until the AB physical connection has been             
                       demonstrated to the required accuracy, the 3.1 sigma confidence of the          
                       BC pair is irrelevant. Hence, we label the entire system as                     
                       undetermined for now, although it is obviously very likely that the             
                       whole system is indeed bound.                                           Jnn2012

                       According to Scardia et al. (2001), this orbit is now well defined and  Sca2001d
                       will certainly change little in the future; only the period is still            
                       slightly uncertain. The Hipparcos parallax is 0".02012 +/- 0.00150.             
                       This gives a mass sum of 2.1 Msun +/- 29%, agreeing very well with              
                       expected values for a system of type G0. Compared to the orbit                  
                       calculated by Scardia in 1980, the total mass of the system, whose      Sca1980e
                       uncertainty was then 55%, is now much better defined. The dynamical             
                       parallax is 0".0193, well in agreement with the measured parallax.
