摘要：
We show that error distributions of a compilation of 28 recent independent measurements of the distance from the Sun to the Galactic center, R-0, are wider than a standard Gaussian and best fit by an n=4 Student's t probability density function. Given this non-Gaussianity, the results of our median statistics analysis, summarized as R-0 = 8.0 +/- 0.3 kpc (2 sigma error), probably provides the most reliable estimate of R-0.
