\tablefoot{\tablefoottext{a}{The names are composed of the selection technique for the source --  AGN, s$BzK$ or p$BzK$ ($\equiv$p$BzK$* here) --  followed by the identification number in our $K$-band ($3.6~\mu$m) catalogue for $BzK$ (AGN) targets.  Sources serendipitously identified are given a simple ``serendip.'' designation.}
\tablefoottext{b}{Q indicates the quality of the redshift, either ``A'' indicating a highly certain redshift, or ``B'' indicating a high level of confidence (see Sect.~3.2).}
\tablefoottext{c}{Magnitudes were derived using SExtractor MAG\_AUTO and are therefore slightly different from the aperture magnitudes used to derive colours for candidate selection.}
\tablefoottext{d}{AGN found within $6\arcsec$ of 7C~1756+6520. No accurate magnitude is available in $K$ due to an artifact caused by a bright star in the near-infrared data. See Fig.~12 in G09.}
