Model orbits have been fitted to 27 physical double stars listed in a 1922 catalog. A Markov Chain Monte Carlo technique was applied to estimate best-fitting values and associated uncertainties for the orbital parameters. Dynamical masses were calculated using parallaxes from the Hipparcos mission and are presented in this paper with the estimates of the orbital parameters for the 27 systems. The resulting mass estimates of the current study are in good agreement with a recently published study, as are comparisons with the orbital parameters listed by the Washington Double Star catalog, confirming the validity of the optimization methodology.

Miller 和 Pitman 研究的马尔可夫链蒙特卡罗优化应用于双星

模型轨道已安装到 1922 年星表中列出的 27 颗物理双星上。应用马尔可夫链蒙特卡罗技术来估计轨道参数的最佳拟合值和相关不确定性。使用依巴谷任务的视差计算动态质量，并在本文中介绍了 27 个系统的轨道参数估计值。当前研究得出的质量估计与最近发表的一项研究非常一致，与华盛顿双星目录列出的轨道参数的比较也是如此，证实了优化方法的有效性。
