摘要：

The "world average" of the astrophysical cross section factor, S-17(0), is driven by the Seattle result due to the very small quoted uncertainty, which we however demonstrate it to be an overestimated accuracy. We propose more realistic error bars for the Seattle results based on the published Seattle data. This leads to a an uncertainty of the measured slope of S-17 and thus an uncertainty due to extrapolation that can be reasonably estimated to be (+0.0)(-3.0) eV-b.
