Number in the total sample of candidates, number of observed candidates, and number of accepted candidates after removal of emission line objects, ``peculiar'' objects (e.g., objects with continuous spectra) and all stars with a~G-band index ${\rm GP} > 6$~{\AA}. In the last column, we list the scaling factors  applied to the [Fe/H]~histograms for each candidate class during the construction of the MDF (see Sect.~\ref{Sect:MDFconstruction}).
