The Archival Pure Parallel Project processed and combined about 2,000 WFPC2 images, primarily in the wide UBVI filters, obtained in parallel with other HST instruments. Combined, drizzled, cosmic-ray cleaned images were produced for each pointing. These data can be used to address a wide range of science topics: measuring the cosmic shear on scales from 20" to 2'; discovering ~ 50 starforming galaxies at z ~ 4; finding optical counterparts to AGNs in wide-area radio and X-ray catalogs; improving the determination of the scale length of the Galactic disk; and studying stellar populations down to 1 solar mass for about 25 separate lines of sight in the Magellanic Clouds.
This catalogue is a copy of the Archived Exposures Catalog (AEC) compiled from the Hubble Space Telescope Data Archive database, with an indication about the existence of scientific images or spectra. It provides a summary of completed HST science observations. This catalogue contains also WFPC2 observations stacked into associations which usage is recommended for a large fraction of the WFPC2 images (see details in the "WFPC2 Associations" section below).
COSMOS (P.I. Nicholas Scoville, California Institute of Technology, USA/CA) is an HST Treasury Program to survey a 2 square degree equatorial field, centered on RA=10:00:28.6 and DEC=+02:12:21.0 with the ACS in the I band of the VIMOS equatorial field. Parallel observations with WFPC2 and NICMOS were also obtained.
GEMs is a large-area (800 arcmin 2) two-color (F606W and F850LP) imaging survey with the Advanced Camera for Surveys on the Hubble Space Telescope. Centered on the Chandra Deep Field-South, it covers an area of ~ 28'x28', or about 120 HDF areas, to a depth of MAB(F606W)=28.5(5s) for compact sources. Focusing on the redshift range ~ 0.2<z<1.1, GEMS provides morphologies and structural parameters for nearly 10,000 galaxies where redshift estimates, luminosities, and SEDs exist from COMBO-17.
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).
