The VLA FIRST (Faint Images of the Radio Sky at Twenty-centimeters)
is a project designed to produce the radio equivalent
of the Palomar Observatory Sky Survey over 10,000 square
degrees of the North Galactic Cap. The
<a href="https://sundog.stsci.edu/top.html"> FIRST home page </a>
has details of the instrumentation, status of the project,
and data available. Currently about 5000 images
of approximately .775x.58 degrees are available.

The Formation and Evolution of Planetary Systems (FEPS) Spitzer Legacy program was designed to characterize the evolution of circumstellar gas and dust around solar-type stars between ages of 3 Myr and 3 Gyr. To achieve these goals, FEPS obtained spectrophotometric observations with the Spitzer Space Telescope for a sample of 328 stars. The observing strategy was to measure the spectral energy distribution (SED) between wavelengths of 3.6 and 70 μm with IRAC and MIPS photometry, and between 8 and 35 μm with low-resolution IRS spectra. In addition, the FEPS program obtained MIPS 160 μm photometry for 80 stars to search for colder dust, and high-resolution IRS spectra for 33 sources to probe for circumstellar gas.
The Frontier Fields is a Spitzer and HST Director's Discretionary program of six deep fields centered on strong lensing galaxy clusters in parallel with six deep "blank fields". These will be the second deepest observations of blank fields and deepest observations of clusters and their lensed galaxies ever obtained.
The first data release contains all archival data taken on these six clusters as well as data taken for the cycle-9 SURFS-UP (PID:90009) program as of April 1, 2013. Improved reductions with better artifact correction and deeper data will be released periodically over the three year period.
IRSA hosts the Spitzer portion of the Frontier Fields data set. For the HST Frontier Fields data, see MAST.
The Galactic Plane Infrared Polarization Survey (GPIPS) covers 76 sq. deg. of the first Galactic quadrant midplane, 18<l<56 deg and -1<b<1 deg, in H-band (1.6 micron) linear polarimetry to reveal the plane-of-the-sky orientation of the magnetic field in diffuse and denser atomic and molecular clouds. The Survey consists of 3234 overlapping 10x10 arcmin fields observed using the Mimir instrument on the 1.8 m Perkins telescope.
The Galaxy Evolution Explorer (GALEX), a NASA Small Explorer mission, is performing the first all-sky, deep imaging and spectroscopic ultraviolet surveys in space. The prime goal of GALEX is to study star formation in galaxies and its evolution with time.
This table contains the Galaxy Evolution Explorer (GALEX) observation log of the extant and planned observations to be made by this satellite observatory. The Galaxy Evolution Explorer (GALEX) is a NASA Small Explorer Mission launched on April 28, 2003. GALEX has been performing the first Space Ultraviolet sky survey. Five imaging surveys in each of two bands (FUV: 1350-1750 Angstroms and NUV: 1750-2800 Angstroms) range from an all-sky survey (limiting m<sub>AB</sub> ~ 20 - 21) to an ultra-deep survey of 4 square degrees (limiting m<sub>AB</sub> ~ 26). Three spectroscopic grism surveys (spectral resolution R = 100 - 300) are underway with various depths (m<sub>AB</sub> ~ 20 - 25) and sky coverage (100 to 2 square degrees) over the 1350 - 2800 Angstroms spectral range. The instrument includes a 50-cm modified Ritchey-Chretien telescope, a dichroic beam splitter and astigmatism corrector, two large, sealed-tube microchannel plate detectors to simultaneously cover the two bands and the 1.2-degree field of view. A rotating wheel provides either imaging or grism spectroscopy with transmitting optics. The GALEX mission also includes an Associate Investigator program for additional observations and supporting data analysis which supports a wide variety of investigations made possible by the first UV sky survey. The HEASARC provides this table of GALEX observations as an assistance to the high-energy astrophysics community, e.g., to enable cross-correlations of GALEX with X-ray observations. The GALEX data are available via MAST at <a href="http://galex.stsci.edu/">http://galex.stsci.edu/</a>. More information about GALEX can be found at <a href="http://www.galex.caltech.edu/">http://www.galex.caltech.edu/</a> and <a href="https://asd.gsfc.nasa.gov/archive/galex/">https://asd.gsfc.nasa.gov/archive/galex/</a>. This table was first created in July 2010 using the input file <a href="http://sherpa.caltech.edu/gips/ref/galex_obs_status.csv">http://sherpa.caltech.edu/gips/ref/galex_obs_status.csv</a> obtained from the Caltech GALEX site. This table is updated within a week of the update of the original file. This is a service provided by NASA HEASARC .
The GALEX, Galaxy Explorer, mission
was launched by a Pegasus-XL vehicle on April 28 2003 into
a 690km altitude, 29 degree inclination, circular orbit with a 98.6
minute period. The GALEX instrument allows imaging and spectroscopic
observations to be made in two ultraviolet bands,
Far UV (FUV) 1350-1780A and Near UV (NUV) 1770-2730A.
The instrument provides simultaneous co-aligned FUV and NUV
images with spatial resolution 4.3 and 5.3 arcseconds respectively.
Details of the performance of the instrument and detectors can be found in
Morrissey et al. (2007) ApJS, 173, 682.
<p>
The <i>SkyView</i> GALEX surveys mosaic the intensity images of
All-Sky Survey images. For a given pixel only the nearest image is used.
Since a given GALEX observation is circular, this maximizes the coverage
compared with default image finding algorithms which use the distance from
edge of the image.

As of February 10, 2011, SkyView uses the GALEX GR6 data release. Provenance: All data is downloaded from the <a href="https://galex.stsci.edu">
