Table B.1: Mean offset, rms ( $\sigma$ ), and rms expected by the errors ( $\sigma$ (exp)) in the comparison between stars observed in Run 4 and in the other runs. The last column shows the z parameter, which indicates the significance of the mean offset. A z-value higher than 1.96 indicates that the offsets are significant with a significance level lower than 0.05.
