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. File Summary:

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.
