We discuss sample selection, photometric properties, and spectral reduction. We derive scale lengths, surface brightnesses, and photometric inhomogeneities from the ACS data and redshifts, stellar velocity dispersions, and [OII] and Hδ equivalent widths from the Keck spectroscopy. Using the published 2Ms Chandra Deep Field-North X-ray catalog (Cat. J/AJ/126/632), we identify active galactic nuclei (AGNs) to clarify the origin of emission lines seen in the Keck spectra. Description: The field was observed using the Deep Imaging and Multi-Object Spectrograph (DEIMOS) at the Keck II telescope on the nights of 2003 April 1-5. File Summary:

Note (1): Morphological type, defined as follows: -1 = Compact; 0 = E; 1 = E/S0; 2 = S0; 3 = Sa+b. Note (2): Photometric parameters through the b4 filter are derived only for objects at z<0.34. Formal GALFIT uncertainties on magnitudes and effective radii are 0.01-0.02mags and a 1-10% in effective radii. Total uncertainties on the combination of photometric parameters that enters the Fundamental Plane log(Re-0.32SBe) are 0.02-0.03. Note (3): All redshifts are quality 4 (certain) except for object 1112 (quality 2, possible), and objects 243, 94, 378, 22, 804, 337, 1382, 1534, 454, 1452 (quality 3, likely). See paper for details. Note (4): In units of Angstroms. [OII] 3727Å and Hδ 4101Å lines.
