Candidates are selected by their UnGR colors using the "BM/BX" criteria to target redshift 1.4~<z~<2.5 galaxies and the LBG criteria to target redshift z∼3 galaxies; combined these samples account for ∼25%-30% of the R and Ks band counts to R=25.5 and Ks(AB)=24.4, respectively. The 212 BM/BX galaxies and 74 LBGs constitute the largest spectroscopic sample of galaxies at z>1.4 in GOODS-N. Extensive multiwavelength data allow us to investigate the stellar populations, stellar masses, bolometric luminosities (Lbol), and extinction z∼2 of galaxies. Deep Chandra and Spitzer data indicate that the sample includes galaxies with a wide range in Lbol (∼1010 to >1012L) and 4 orders of magnitude in dust obscuration (Lbol/LUV). Description: The imaging, photometry, color selection, and spectroscopic observations of galaxies in the fields of our survey are described in several other papers published by our group (Steidel et al. 2003, Cat. J/ApJ/592/728, 2004ApJ...604..534S; Adelberger et al., 2004ApJ...607..226A; Reddy et al., 2005ApJ...633..748R). Specific details regarding the GOODS-N optical imaging are presented in Reddy et al. (2005ApJ...633..748R). File Summary:
