标题： A New Estimate of the Best Value for the Solar Galactocentric Distance

摘要： 使用文献中的数据，我们列出了自2017年后通过不同方法得出的太阳银道距离的个体估计值。 这些值尚未用于计算平均值$R_0$。对于包含21个估计值的样本，基于标准方法，我们发现加权平均值为${\overline R_0}=8.14$千秒差距，离散度为$\sigma=0.16$千秒差距，并且使用中位数统计法，我们得到的估计值为$R_0=8.15\pm0.11$千秒差距。 为了实际应用，推荐值为$R_0=8.1\pm0.1$千秒差距。 显示英文摘要

摘要： Using data from the literature, we made a list of individual estimates of the solar Galactocentric distance, which were performed after 2017 by different methods. These values have not yet been used to calculate the best value of mean $R_0$. For the sample containing 21 estimates, based on the standard approach, we found the weighted mean ${\overline R_0}=8.14$ kpc with the dispersion $\sigma=0.16$ kpc, and using the median statistics, we obtained the estimate $R_0=8.15\pm0.11$ kpc. For practical use, the value $R_0=8.1\pm0.1$ kpc can be recommended.
