                       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.

                       the magnitude difference is about 2.5.

                       the Struve pairs, which seemed a good first step, was hampered by the           
                       quadrant error of the pair he designated Ca. This quadrant error was            
                       repeated in the ADS, IDS, and in earlier editions of the WDS. In the            
                       ADS (where this pair is listed as #2984, but note that #2989 is part            
                       of this system, too) the errors multiplied. The pair Holmes AF (WDS

                       evidence of duplicity was found.  If this additional component is

                       those for HR 1331 (= McA 14) for the same epoch. These two stars were

                       same data set, but with different scale factors; the HR 1331 measure            
                       for 1988.6582 is the correct one.  Reanalysis of the correct data for

                       as a triple by Galileo on 4 February 1617. It was independently found           
                       as a triple in 1656 by Christian Huygens, who is often given credit             
                       for recognizing this multiple system. Theta Orionis D was found by      A__1935f
                       Abbe Jean Picard, as documented by a manuscript drawing of 20 March             
                       1673. The D component was independently found by Huygens in 1684. A is          
                       an Algol-type system, V1016 Ori. B is an Algol-type system, BM Ori. C
