This survey is a deep, high resolution radio survey of a relatively small region that has particularly deep coverage
in the Sloan Digital Sky Survey. As described in the reference abstract:
This is a high-resolution radio survey of the Sloan Digital Sky Survey (SDSS) Southern Equatorial
Stripe, a.k.a., Stripe 82. This 1.4 GHz survey was conducted from 2007 to 2009 with the Very Large Array primarily in the A-configuration,
with supplemental B-configuration data to increase sensitivity to extended structure.
The survey has an angular resolution of 1.8" and achieves a median rms noise of 53 microJy/beam over 92 square degrees.
This is the deepest 1.4 GHz survey to achieve this large of an area filling in the
phase space between small&deep and large&shallow surveys.
<p>
The astrometric accuracy of the data is excellent with errors in observed sources of 0.10" in both RA and declination.
A comparison with the SDSS DR7 Quasar Catalog confirms that the astrometry is well tied to the optical reference
frame with mean offsets of 0.02+/-0.01" in RA and 0.01+/-0.02 in declination. Provenance: TBD. This is a service of NASA HEASARC.
VLT ISAAC Ks Observations of the Southern Hubble Ultradeep Field

Description:
A very deep Ks observation of the Hubble Ultradeep Field. This observation is
approximately 0.6 magnitudes deeper than the GOODS ISAAC Ks image but covers
only small fraction of the area. Provenance: Data downloaded from VLT archive. This is a service of NASA HEASARC.
The Westerbork Northern Sky Survey (<i>WENSS</i>) is a low-frequency
radio survey that covers the whole sky north of delta=30 degree at a
wavelength of 92 cm to a limiting flux density of approximately 18 mJy
(5 sigma). This survey has a resolution of 54" x 54" cosec (delta)
and a positional accuracy for strong sources of 1.5''.

The WFPC2 is used to obtain high resolution images of astronomical objects over a relatively wide field of view and a broad range of wavelengths (1150 to 11,000 Å).
The WF/PC-1 was used from April 1990 to November 1993, to obtain high resolution images of astronomical objects over a relatively wide field of view and a broad range of wavelengths (1150 to 11,000 Angstroms).
Spectra from the Univsity of Wisconsin Pine Bluff Observatory
in the 3,200 - 7,750 Å range, resolution ~ 80, V_max ~ 15, ~ 2800 observations
of ~ 400 targets, 1989-1998. Note spectropolarimetry data is also included.
Observations complement those obtained from the ASTRO WUPPE project.
UV spectra in the 1,400 - 3,200 Å range, resolution ~ 140, V_max ~ 14,
~ 400 observations of ~ 200 targets, 2 NASA-funded shuttle missions (12/90 & 3/95).
Note spectropolarimetry data is also available.
The Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) was the spectropolarimetry component of the three ASTRO instruments that flew on Space Shuttle missions in December 1990 and March 1995. A halfwave spectropolarimeter provided medium resolution spectropolarimetry for research into the interstellar medium, hot stars, stars with circumstellar material, interacting binary stars, novae, solar system objects, and active galaxies. A Lyot analyzer obtained low resolution observations of faint targets, but due to calibration problems did not produce scientifically useful data. The WUPPE instrument provides a unique data set, one of the few providing polarimetric data in the ultraviolet portion of the spectrum.
WISE 3\.4 Micron All-Sky Survey>: All-WISE data release
Short Name:
WISE
Date:

NASA/GSFC HEASARC
Description:
From the <a href="https://wise2.ipac.caltech.edu/docs/release/allsky">WISE mission site:</a>.
<hr>
NASA's Wide-field Infrared Survey Explorer (WISE) mapped the
sky at 3.4, 4.6, 12 and 22 micrometers in 2010 with an
angular resolution of 6.1", 6.4", 6.5" and 12.0" in the four bands.
WISE achieved a 5 sigma point source sensitivities better and 0.08, 0.11
1 and 6 mJy in unconfused regions on the ecliptic in the four
bands. Sensitivity improves toward the ecliptic poles due to denser
coverage and lower zodaical background.
<p>
The WISE All-WISE
includes all data taking during the WISE full cryogenic phase, from January 7, 2010 to August 6, 2010, that were processed
with improved calibrations and reduction algorithms and combines this with the NEOWISE postcryogenic
survey to form the most comprehensive view of the full mid-infrared sky.

SkyView includes the four WISE bands as separate surveys. Many non-image
data products are available at the WISE site. Note that WISE data is
distributed in relatively large (>50 MB) image files. When SkyView generates
an image for a part of the sky where it has not yet cached the
data from the IPAC server there may be a delay as full tiles are downloaded
even when only a small fraction of a tile is needed. Images
in cached regions, are generated much faster. Access to
the WISE data uses the VO SIA interface maintained at IPAC. Even when
data is cached, the SIA service must still be available for successful
queries. Provenance: WISE Archive (IRSA/IPAC). This is a service of NASA HEASARC.
