Table 3: Spatial distribution of $\ensuremath {{E}({B}-{V})}$ colour excess as measured in the South field. In Col. 3 we report the measured rms of the $\ensuremath {{E}({B}-{V})}$ distribution, in Col. 4 the mean error on $\ensuremath {{E}({B}-{V})}$ resulting from the fitting procedure (see text), whereas Col. 5 lists the intrinsic reddening dispersion, computed as the quadratic difference of the first two quantities. The number of stars with direct extinction determination is shown in the last column.
