Abstract:
We present a table of redshifts for 2907 galaxies and stars in the
145arcmin2 HST ACS GOODS-North, making this the most spectroscopically
complete redshift sample obtained to date in a field of this size. We
also include the redshifts, where available, in a table containing
just under 7000 galaxies from the ACS area with Ks,AB<24.5 measured
from a deep Ks image obtained with WIRCam on the CFHT, as well as in
a table containing 1016 sources with NUVAB<25 and 478 sources with
FUVAB<25.5 (there is considerable overlap) measured from the deep
GALEX images in the ACS area. Finally, we include the redshifts, where
available, in a table containing the 1199 24um sources to 80uJy
measured from the wider area Spitzer GOODS-North. The redshift
identifications are greater than 90% complete to magnitudes of
F435WAB=24.5, F850LPAB=23.3, and Ks,AB=21.5, and to 24um fluxes
of 250uJy. An extensive analysis of these data appear in a companion
paper, but here we test the efficiency of color-selection techniques
to identify populations of high-redshift galaxies and active galactic
nuclei. We also examine the feasibility of doing tomography of the
intergalactic medium with a 30m telescope.
Description:
We take the optical photometric data from existing work. In
particular, we take the U magnitudes from Capak et al. (2004, Cat.
J/AJ/127/3121) and the F435W, F606W, F775W, and F850LP magnitudes from
the HST Advanced Camera for Surveys (ACS) observations of the GOODS-N
(Giavalisco et al. 2004, Cat. II/261).
We have obtained new ultradeep Ks images from the Wide-field
Infrared Camera (WIRCam) on the CFHT 3.6m telescope in semesters 2006A
and 2007A and from the Multi-Object Infrared Camera and Spectrograph
(MOIRCS) on the Subaru 8.2m telescope, taken between 2005 December and
2008 January.
Spectral observations for the ACS GOODS-N field were made over
a number of DEIMOS (Deep Extragalactic Imaging Multi-Object
Spectrograph) runs between 2004 and 2007.

Note (1): [b] We have not distinguished the observations made in the Barger
et al. (2003, Cat. J/AJ/126/632) paper (literature source 12) from our
DEIMOS and LRIS observations of the ACS GOODS-N area (literature
sources 1 and 3), which is why zeros appear in the number and unique
columns for Barger et al. (2003, Cat. J/AJ/126/632). However, we
retain Barger et al. (2003, Cat. J/AJ/126/632) as a literature source
in this table because it includes some ESI identifications that appear
in the 24um catalog outside the ACS GOODS-N area.
--------------------------------------------------------------------------------
Global notes:
Note (G1): For negative flux in the aperture, we show the magnitude
corresponding to the absolute flux with a minus sign in front.
Note (G2): Flag on redshift has the following meaning:
s = star;
n = no id;
w = spectroscopic redshift separated by more 1.5 arcseconds from
24um position, these counterparts should be treated with caution;
u = no observation;
: = uncertain redshift.
