Table 6: Comparison of measured scatter in Figs. 17 and 18 with relative errors in the abundance ratios. For each plot we report the minimum, mean and maximum measured $1\sigma$ scatter $\sigma _{\rm meas}$ across the range of [Fe/H] or [Mg/H], which is compared to the average relative error in the abundance ratio $\sigma ^{\rm rel}$ . The ratio of the mean measured scatter to the estimated error $\langle \sigma_{\rm meas} \rangle /\sigma^{\rm rel}$ is reported in the last column.
