Notes:\\
$^\star$ Detailed information about each source is given in Sect.~\ref{comments}.\\
$^1$ The characters in parenthesis after the IAU names codify the radio survey
from where the object was selected as follows:\\
(oo) Ooty lunar occultation survey at 327~MHz; (ml) Molonglo surveys (MC~1 and MC~2) at 408~MHz;
(mg) MIT (365~MHz)~-- Green-Bank (4.8~GHz) survey; (gb) Green-Bank (1.4~GHz)~-- Molonglo (408~MHz) survey.\\
$^2$ The positions refer to the radio peak for unresolved sources and to the central radio component if detected. For the remaining sources, the mid-point between the lobes is adopted (see Fig.~\ref{overlays}).\\
$^3$ Radio morphology: D (Double), T (Triple), SR (Slightly Resolved),
R (Resolved), U~(Unresolved).\\
$^4$ The radio fluxes are given at 408~MHz, except the values in parenthesis that correspond to 327~MHz.\\
$^5$ The codes for the optical observations~(I,~S) are as defined in Tables~\ref{imaging} and~\ref{spectra}. Exposure times for imaging ranged between ten and 30~min at the ESO 3.6~m/NTT 3.5~m telescopes, and 20 and 60~min at the ESO 2.2~m/Danish 1.5~m telescopes. Exposure times for
spectroscopy are given together with the comments for each source. The letters~"a'', "b'' and~"c'' refer to the quality of the astrometry as described in
Sect.~\ref{astrometry}. Asterisks refer to the sources for which our
spectroscopic data did not yield redshift (see Sect.~\ref{redshifts}). References to published observations are given in Sect.~\ref{comments}.
