The Ultraviolet Imaging Telescope UIT was one of three ultraviolet telescopes on the ASTRO-1 mission flown on the space shuttle Columbia during 2-10 December 1990. The same three instruments were later flown on the space shuttle Endeavour from 3-17 March 1995, as part of the ASTRO-2 mission. Exposures were obtained on 70-mm photographic film in the 1200-3300 Å range using broadband filters and later digitized using a Perkin-Elmer microdensitometer. Image resolution was 3" over a 40' field of view. Overall, UIT-1 obtained 821 exposures of 66 targets, and UIT-2 obtained 758 images of 193 targets.
The Newton X-ray Multi-Mirror Mission (XMM) was launched in December, 1999 with a projected lifetime of 10 years. Although intended primarily as an X-ray observatory, XMM included a small but powerful optical/UV 30 cm telescope co-aligned with the X-ray telescopes for contemporaneous observations. The modified Ritchey-Chretien telescope is capable of detecting 24th magnitude sources in its 17 arcmin field of view. It provides images in the 160-600nm wave band with 1 arcsec resolution. MAST is serving a OM Mosaic product that uses a pipeline described by Kuntz et. al. OMCat: Catalog of Serendipitous Sources Detected with the XMM-Newton Optical Monitor PASP, 120:740-758
VLA Faint Images of the Radio Sky at Twenty Centimeters (FIRST)

Space Telescope Science Institute Archive
Description:
Faint Images of the Radio Sky at Twenty-cm (FIRST) is a systematic survey of the North and South Galactic caps begun in 1993, using the NRAO Very Large Array (VLA) . Typical images are comprised of 1150x1550 1.8" pixels with 5" resolution. Source catalogs are also available including peak and integrated flux densities generated from the high resolution coadded images. The survey yields very accurate (<1 arcsec rms) radio positions of faint (>1 mJy/beam) compact sources. The areas observed were chosen to coincide with the Sloan Digital Sky Survey.
Space Telescope A901/902 Galaxy Evolution Survey (STAGES)
Short Name:
HST.STAGES

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.
Hubble Space Telescope Snapshots of 3CR Radio Galaxies
Short Name:
HST.3cr

Space Telescope Science Institute Archive
Description:
The revised 3C catalogue (3CR, Bennett 1962) forms a flux-limited sample of the most radio-powerful sources in the northern hemisphere. Over the decade and a half of HST operation we have performed "snapshot" imaging from the near-IR to the near-UV of a large number of these sources. Most recently we have completed a NICMOS 1.6 micron survey of low-redshift (z less than 0.3) 3CR sources (Madrid et al. 2006, Floyd et al 2008). The fully-reduced data for all 101 sources included in those papers are presented here in numerical order.
Hubble Space Telescope multi-color ACS mosaic of M82

Publisher:
Space Telescope Science Institute Archive
Description:
In March 2006, the Hubble Heritage Team obtained a large 4-color (B, V, I, and H-alpha) mosaic image of the M82 with the Advanced Camera for Surveys (ACS) onboard the Hubble Space Telescope.
Hubble Space Telescope Heritage Press Release Images
Short Name:
HST.heritage
Date:

Publisher:
Space Telescope Science Institute Archive
Description:
WFPC2 and ACS images used to create the Heritage project color composite press releases. The data has been expertly prepared, significantly beyond the standard pipeline processing. This usually involves careful image registration, combination, and cleaning via drizzling, making it ready for further scientific analysis and educational use. These data will typically be made available at the time of the associated press release.
Hubble Space Telescope ACS Nearby Galaxy Survey (ANGST)
Short Name:
HST.angst

Space Telescope Science Institute Archive
Description:
The ACS Nearby Galaxy Survey observed roughly 14 million stars in 69 galaxies. The survey explored a region called the "Local Volume," and the galaxy distances ranged from 6.5 million light-years to 13 million light-years from Earth. The Local Volume resides beyond the Local Group of galaxies, an even nearer collection of a few dozen galaxies within about 3 million light-years of our Milky Way Galaxy. The observations were made in November 2006 with Hubble's Advanced Camera for Surveysi (ACS).
Holwerda et al. examined 32 HST/WFPC2 archival fields of 29 spiral galaxies (Sab and later) for their paper The Opacity of Spiral Galaxy Disks. IV. Radial Extinction Profiles from Counts of Distant Galaxies Seen through Foreground Disks (2005, AJ,129:1396-1411). The majority of the data are from the Cepheid distance scale Key Project. The explicit goal was to provide deep mosaics in both V- and I-band with a better sampling in order to identify background galaxies through the foreground disk.
A second Hubble Deep Field campaign was carried out between late September and October of 1998. The raw, pipeline calibrated and reprocessed data were released to the community on November 23, 1998. The rationale for undertaking a second deep field campaign followed from the wealth of information that has come out of HDF-N, and from the desire to provide a point of focus for similar studies of the distant universe from southern-hemisphere facilities. Simultaneous, parallel observations were made with the three HST instruments STIS, WFPC2 and NICMOS of separate, neighboring fields. As was the case for HDF-N, approximately 150 consecutive orbits were devoted to a single telescope pointing.
