Notes --
The 66 masks listed in this table are the masks with long exposures
(with the exception of the listed 1238.5$-$1144 mask,
cf.\ Sect.~\ref{sec:obs}).
Each field has between 1 and 5 such masks. The masks are numbered
from 01 to 11 as described in \citet{Halliday_etal:2004}.
For reference the column $\zclfinal$ lists the
spectroscopic~cluster redshifts
(\citealt{Halliday_etal:2004} and this paper);
these~cluster redshifts were determined from all the obtained spectroscopy
and were not as such part of the spectroscopic target selection.
Where more than one redshift is listed the order is as follows:
main~cluster, secondary~cluster ``a'', secondary~cluster ``b''
(cf.\ Sect.~\ref{sec:zhist}).
The ``Explanation'' column gives the same information as the
$\zphotlow$ and $\zphothigh$ columns, except for a possible rounding to two decimals.
The ``Filters'' column indicates what photometric data were
employed to calculate
the photometric redshifts used in the spectroscopic target selection.
Filters in brackets indicate data \emph{not} employed;
these data were obtained
later and used in subsequent studies, e.g.\ to calculate the final EDisCS
photometric redshifts (Pell{\'o} et~al., in prep.).
No data are listed for the 1122.9$-$1136 field, since it only has
an initial short mask, no long masks, cf.\ Sect.~\ref{sec:obs}.
