The 1897 measure by Burnham was "... made under not the best |
Bu_1900 |
|
conditions ..." and "... is difficult to reconcile ...". Aitken did |
|
|
not include it in the ADS. It was, then, not in the IDS list of |
A__1932a |
|
measures transferred to Washington in 1964, so this measure was lost |
IDS1963A |
|
for many years and recently found by G. Torres, and the observation |
Trr2019 |
|
of this high eccentricity binary was made shortly after periastron |
|
|
passage, which resulted in the unexpected result. |

|
Ma = 1.63 (+0.30 or -0.13) \msun, Mb = 1.11 (+0.21 or -0.14) \msun, |

orbital parallax = 20.984+/-0.060 mas. |
