Abstract:
We explore the evolution of field early-type galaxies in a sample
extracted from the ACS images of the southern GOODS field. The
galaxies are selected by means of a nonparametric analysis, followed
by visual inspection of the candidates with a concentrated surface
brightness distribution. We furthermore exclude from the final sample
those galaxies that are not consistent with an evolution into the
Kormendy relation between surface brightness and size that is observed
for z=0 ellipticals. The final set, which comprises 249 galaxies with
a median redshift zm=0.71, represents a sample of early-type systems
not selected with respect to color, with similar scaling relations as
those of bona fide elliptical galaxies.

Note (1): Three source identifications are not in the GOODS format:
ID44.1118, ID33.1024, and ID44.1636.
Note (2): The type corresponds to the spectral template that gives the
best fit to the photometric redshift. Six templates are used,
interpolating in 1/3 steps between them. Types 1 to 4 refer
to E, Sbc, Scd and Im SEDs from Coleman, Wu & Weedman
(1980ApJS...43..393C 1980ApJS...43..393C). Types 5 and 6 correspond to starburst
SB2 and SB3 templates from Kinney et al. (1996ApJ...467...38K 1996ApJ...467...38K).
Note (3): About the best linear fit to the color radial distribution).
The scatter is obtained from the biweight measure of scale
(Beers, Flynn & Gebhardt, 1990AJ....100...32B 1990AJ....100...32B) which is much
more robust with respect to the presence of outliers.
