Abstract:
We present initial results from the Great Observatories Origins Deep
Survey (GOODS) that are primarily, but not exclusively, based on
multiband imaging data obtained with the Hubble Space Telescope and
the Advanced Camera for Surveys (ACS). The survey covers roughly 320
arcmin2 in the ACS F435W, F606W, F814W, and F850LP bands, divided into
two well-studied fields. Existing deep observations from the Chandra
X-Ray Observatory and ground-based facilities are supplemented with
new, deep imaging in the optical and near-infrared from the European
Southern Observatory and from the Kitt Peak National Observatory. Deep
observations with the Space Infrared Telescope Facility are scheduled.
Reduced data from all facilities are being released worldwide within
36 months of acquisition. Together, this data set provides two deep
reference fields for studies of distant normal and active galaxies,
supernovae, and faint stars in our own Galaxy. This Letter serves to
outline the survey strategy and describe the specific data that have
been used in the accompanying letters, summarizing the reduction
procedures and sensitivity limits.
Description:
source identification and photometry were performed using SExtractor
(Bertin & Arnouts, 1996A&AS..117..393B 1996A&AS..117..393B)

--------------------------------------------------------------------------------
Note (1): The flags are coded in decimal, all the extraction flags as a
sum of powers of 2, as follows:
1 = The object had neighbours, bright and close enough to
significantly bias the MAG_AUTO photometry, or bad pixels
(more than 10% of the integrated area affected)
2 = The object was originally blended with another one
4 = At least one pixel of the object is saturated (or very close to)
8 = The object is truncated (too close to an image boundary)
16 = Object's aperture data are incomplete or corrupted
32 = Object's isophotal data are incomplete or corrupted
64 = A memory overflow occured during deblending
128 = A memory overflow occured during extraction
