SkyView is a Virtual Observatory on the Net. Astronomers can generate images of any portion of the sky at wavelengths in all regimes from radio to gamma-ray. Users tell
SkyView the position, scale and orientation desired, and SkyView gives users an image made to their specification. The user need not worry about transforming between
equinoxes or coordinate systesm, mosaicking submaps, rotating the image,.... SkyView handles these geometric issues and lets the user get started on astronomy.
The Sloan Digital Sky Survey is the deepest large scale survey of the
sky currently available. SkyView dynamically queries the SDSS archive
(current release DR16) to retrieve data and resample it into the user
requested frame. All releases after DR9 are spectra only, so all imaging data
originates from DR9. Further information about SDSS and many additional services
are available at the <a href="https://www.sdss.org">SDSS website</a>. Provenance: Sloan Digital Sky Survey Team. This is a service of NASA HEASARC.

Southern GOODS Field: VLT ISAAC Observations, H band
Short Name:
GOODS ISAAC H
Date:
18 Apr 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:
18 Apr 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:
23 Jul 2020 19:41:16
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 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.
The Spitzer Infrared Nearby Galaxy Survey is a comprehensive infrared imaging and spectroscopic survey of 75 nearby galaxies. Its primary goal is to characterize the infrared emission of galaxies and their principal infrared-emitting components, across a broad range of galaxy properties and star formation environments. SINGS provides new insights into the physical processes connecting star formation to the interstellar medium properties of galaxies and provides a vital foundation for understanding infrared observations of the distant universe and ultraluminous and active galaxies.
