The Hubble Deep Field (HDF) is a Director's Discretionary program on HST in Cycle 5 to image a typical field at high galactic latitude in four wavelength passbands as deeply as reasonably possible. In order to optimize observing in the time available, a field in the northern continuous viewing zone (CVZ) was selected and images were taken for 10 consecutive days, or approximately 150 orbits. Shorter 1-orbit images were also obtained of the fields immediately adjacent to the primary HDF in order to facilitate spectroscopic follow-up by ground-based telescopes. The observations were carried out from 18-30 December 1995, and the data are available to the community for study.
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.
For the 14 hours of peak Leonid meteoroid flux in November 2002, the Hubble Space Telescope was pointed away from the radiant, and the solar arrays were oriented to minimize their cross-section. By coincidence, one of the nearest and largest planetary nebulae, the Helix Nebula (NGC 7293), was nearly opposite the incoming Leonids and could be observed. A "Hubble Helix Team" (below) of volunteers led by Margaret Meixner (STScI) organized a nine-orbit campaign to observe the Helix with the ACS, WFPC2, NICMOS, and STIS.
MAST-produced spectral container files for STIS spectra. STIS
spectra range from 1150 to 10,300 at low to medium spectral resolution, high
spatial resolution echelle spectroscopy in the ultraviolet. STIS began
operation in 1997. (Note the included echelle spectra are technically not
yet supported by the SSAP.)
The "TNO Search Field" images are the sidereally summed images of a search for trans-Neptunian objects (TNOs) using the Wide Field Camera of the HST/ACS instrument. The observations were taken under Cycle 11 program GO-9433, "The Size Distribution of Kuiper Belt Bodies," with G. Bernstein as PI. The TNO search consisted of approximately 96x400 s exposures in the F606W filter for each of six contiguous ACS fields of view. The TNO search field is approximately 6'x10', centered near 14h 07M 53.3s -11d 21' 38" (J2000).
The ACS Ultra Deep Field (UDF) is a cycle 12 survey carried out using the Advanced Camera for Surveys (ACS) on HST and taking advantage of the Director's Discretionary time. The UDF consists of a single ultra-deep field (412 orbits in total taken in 4 bands) within the CDF-S GOODS area. It is the deepest image ever obtained with Hubble. This service also includes data from the UDF follow-Up program by PI Massimo Stiavelli and colleagues obtained under HST cycle 14 program 10632 titled Searching for galaxies at z>6.5 in the Hubble Ultra Deep Field (also known as UDF05).
A pictorial atlas of UV (2300 Å) images, obtained with the Hubble Space Telescope (HST) Faint Object Camera, of the central 22''× 22'' of 110 galaxies (Maoz, Filippenko, Ho, Macchetto, Rix, & Schneider 1996). The observed galaxies are an unbiased selection constituting about one half of a complete sample of all large (D>6 arcmin) and nearby (V< 2000 km/s ) galaxies. This is the first extensive UV imaging survey of normal galaxies. The data are useful for studying star formation, low-level nuclear activity, and UV emission by evolved stellar populations in galaxies. At the HST resolution (~ 0.05''), the images display an assortment of morphologies and UV brightnesses. These include bright nuclear point sources, compact young star clusters scattered in the field or arranged in circumnuclear rings, centrally-peaked diffuse light distributions, and galaxies with weak or undetected UV emission. We measure the integrated ~2300 Å flux in each image, and classify the UV morphology.
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.

Description:
Hubble Infrared Pure Parallel Imaging Extragalactic Survey (HIPPIES) utilizes long-duration pure parallel
visits (~> 3 orbits) of HST at high Galactic latitude (|b|>20o) to take deep, multi-band images in WFC3
(since Cycle 17) and in ACS (starting Cycle 18). It is unique in its large number of descrete fields
along random sightlines, and thus is complementary to other surveys over contiguous fields but
along limited sightlines.
The Hubble Space Telecope Legacy Archive (HLA) was developed at the Space Telescope Science Institute to optimize the science return from HST instruments. This resource is an image service which accesses all HLA observation data. The calibrated data is fully online with several forms of access including footprint visualization, composite images, extracted spectra and source lists.
