Abstract
We show that error distributions of a compilation of 28 recent independent measurements of the distance from the Sun to the Galactic center, R0, 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 (2σ error), probably provides the most reliable estimate of R0.
