Abstract:
We present a candidate sample of luminous bulges (including
ellipticals) found within the Groth Strip Survey (GSS), with
spectroscopic redshifts of 0.73<z<1.04 from the Keck Telescope. This
work is distinguished by its use of two-dimensional two-component
decomposition photometry from Hubble Space Telescope (HST) images to
separate the bulge from any disk before applying the sample selection
and to measure disk-free colors. We define a statistically complete
sample of 86 bulges with r1/4 profiles and luminosities brighter
than IAB=24. Although larger samples of distant early-type galaxies
exist, this is the largest and most homogeneous sample of bulges at
z∼1 with spectroscopy. A brighter subset of 52 objects with added
structural constraints defines our "quality sample" that is used to
explore bulge luminosities and colors.

Global Notes:
Note (G1): * indicates the source belongs to quality sample (see Section 3.4).
Note (G2): Source ID is given by FFC_XXYY, where FF is the subfield, C is the
WFPC2 chip number, and XX and YY are the chip coordinates in units
of 10 pixels (Koo et al. 1996ApJ...469..535K 1996ApJ...469..535K).
Note (G3): From the GIM2D fits and Monte Carlo samplings and do not include any
systematic or random errors that can be derived from simulations
(see Cat. J/ApJS/142/1 and Section 2.1).
