Southern GOODS Field: VLT ISAAC Observations, H band
Short Name:
GOODS ISAAC H
Date:
07 Mar 2025
Publisher:
NASA/GSFC HEASARC
Description:
As part of the Great Observatories Origins Deep Survey (GOODS),
near-infrared imaging observations of the Chandra Deep Field South (CDF-S)
were carried out in J, H, Ks bands, using the ISAAC instrument mounted at
the Antu Unit Telescope of the VLT at ESO's Cerro Paranal Observatory, Chile.
<p>
These data were obtained as part of the ESO Large Programme 168.A-0485 (PI: C. Cesarsky).
Data covering four ISAAC fields in J and Ks bands were also drawn from the ESO programmes 64.O-0643, 66.A-0572 and 68.A-0544 (PI: E.Giallongo),
which were part of the previous data releases.
<p>
This data release covers 172.4, 159.6, and 173.1 arcmin2 of the GOODS/CDF-S
region in J, H and Ks respectively. More than 50% of the images reach a 5-sigma depth
for point sources of at least 25.2 mag (J), 24.7 mag (H and Ks) in the AB system ("median depth").
<p>
This final GOODS/ISAAC data release accumulates observational data which have
been acquired in 12814 science integrations between October 1999 and January 2007
totaling 1.3 Msec integration time.

Southern GOODS Field: VLT VIMOS Observations, R band
Short Name:
GOODS VIMOS R
Date:
07 Mar 2025
Publisher:
NASA/GSFC HEASARC
Description:
As part of the Great Observatories Origins Deep Survey (GOODS),
deep imaging in the Chandra Deep Field South (CDF-S) has been carried out,
using the VIMOS instrument mounted at the Melipal Unit Telescope of
the VLT at ESO's Cerro Paranal Observatory, Chile.
<p>
This data release contains the coadded images in U band from the ESO large programme
168.A-0485 (P.I. C. Cesarsky) which have been obtained in
service mode observations between August 2004 and fall 2006.
The 1-sigma depth for VIMOS U band in the area covered by the GOODS-ACS observations
is ~30 AB (within an aperture of 1" radius, ranging from 29.5 and 30.2 AB).
The PSF of the VIMOS U band mosaic is ~0.8" FWHM, but varies over the field.
<p>
Also included in this data release is a coadded image in R band obtained from
data retrieved from the ESO archive. Due to the different observing strategies
adopted in the programmes the resulting coverage of the GOODS-ACS
area is more complex than for the U band.
The depth of the VIMOS R band mosaic over the ACS area ranges from ~28 AB to 29 AB
(1-sigma, 1" aperture radius).
The PSF of the VIMOS R band mosaic is ~0".7 FWHM and varies over the field.

Space Telescope A901/902 Galaxy Evolution Survey (STAGES)
Short Name:
HST.STAGES
Date:

Publisher:
Space Telescope Science Institute Archive
Description:
STAGES is a large area (0.5x0.5 degree) survey of the complex Abell 901(a,b)/902 multiple-cluster system at z=0.165. An 80-tile imaging mosaic in F606W was conducted in HST cycle 13 with the HST/ACS instrument.
The Spitzer Archival FIR Extragalactic Survey (SAFIRES) is an offshoot of the Spitzer Space Telescope Enhanced Imaging Products (SEIP). SAFIRES applies the SEIP project's methods to the remaining two MIPS bands, located at far-infrared wavelengths of 70 and 160 microns. Due to the complexity of far-infrared observations, these bands require an expansion of SEIP's standard pipeline through the addition of reprocessing tools. These additional steps are required to remove obvious artifacts before extracting useful measurements. As a result, these bands were not included in the SEIP project, but were later funded through an additional NASA Astrophysics Data Analysis Program (ADAP) grant. To ensure high reliability, the SAFIRES sample includes no fields near the Galactic disk; these observations comprised more than half of the area observed by Spitzer, but the practical drawbacks of Galactic contamination would inhibit the ability to maintain the level of reliability desired in the SAFIRES products. As with SEIP, the SAFIRES source lists contains no extended sources. The remaining sample comprises nearly 1132 fields spanning almost 180 square degrees of sky.
Spitzer-Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey
Short Name:
S-CANDELS
Date:
27 Oct 2022 19:00:00
Publisher:
NASA/IPAC Infrared Science Archive
Description:
The Spitzer-Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (S-CANDELS) is a Spitzer Cycle 8 Exploration Program (PI G. Fazio) that obtained deep IRAC channel 1 and 2 imaging in five widely separated extragalactic fields: the UKIDSS Ultra-Deep Survey (UDS), the Extended Chandra Deep Field South (ECDFS), COSMOS, the HST Deep Field North (HDFN), and the Extended Groth Strip (EGS). S-CANDELS builds upon the existing coverage of these fields obtained as part of the Spitzer Extended Deep Survey (SEDS), a Cycle 6 Exploration Program, by increasing the integration time from 12 hours to a total of 50 hours within a smaller area of 0.16 deg2.
The Spitzer Deep Wide-Field Survey is a four-epoch survey of roughly 10 square degrees of the NOAO Deep, Wide-Field Survey field in Boötes. The first visit to the field occurred very early in the Spitzer mission, in 2004 January, as part of the IRAC Shallow Survey (Eisenhardt et al. 2004). Subsequent visits to the field as part of the SDWFS program reimaged the same area to the same depth.
The Spitzer Science Center and IRSA have released a set of Enhanced Imaging Products (SEIP) from the Spitzer Heritage Archive. These include Super Mosaics (combining data from multiple programs where appropriate) and a Source List of photometry for compact sources. The primary requirement on the Source List is very high reliability -- with areal coverage, completeness, and limiting depth being secondary considerations. The SEIP include data from the four channels of IRAC (3.6, 4.5, 5.8, 8 microns) and the 24 micron channel of MIPS. The full set of products for the Spitzer cryogenic mission includes around 42 million sources.
SERVS is a warm Spitzer survey which images approximately 18 square degrees in the centers of the SWIRE XMM-LSS, ELAIS-S1, CDFS, Lockman and ELAIS-N1 fields to 20min (2mu Jy) depth at 3.6 and 4.5 microns. SERVS overlaps with the VISTA-VIDEO near infrared and Herschel-HERMES and SCUBA2-S2CLS far-infrared surveys.
The Spitzer Extragalactic First Look Survey is composed of 4 square degrees of imaging with MIPS and IRAC centered at J1718+5930. Ancillary data are available from a wide variety of optical and radio observatories.
The Spitzer/HETDEX Exploratory Large-Area (SHELA) survey covers ~24 sq. deg at 3.6 and 4.5 microns. The survey area falls within the footprints of the Sloan Digital Sky Survey "Stripe 82" region, the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), and the Dark Energy Survey. The images and catalogs are 80% (50%) complete to limiting magnitudes of 22.0 (22.6) AB mag in the detection image, which is constructed from the weighted sum of the IRAC 3.6 and 4.5 micron images. The catalogs reach limiting sensitivities of 1.1 microJy at both 3.6 and 4.5 microns (1#, for R = 2" circular apertures).
