The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope by
combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA)
into a single master catalog.
The Hubble Source Catalog (HSC) detailed search
displays an entry for each separate detection (or nondetection if nothing is found at that position)
using all the relevant Hubble observations for a given object
(i.e., different filters, detectors, separate visits).
The catalog currently contains over 100 million entries.
The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope
by combining the tens of thousands visit-based source lists in the Hubble Legacy Archive (HLA)
into a single master catalog.
The HSC Summary search displays a single row entry for each object,
as defined by a set of detections that have been cross-matched and hence are believed to be a single object.
Averaged values for magnitudes and other relevant parameters are provided.
The catalog currently contains over 16 million entries.
Hubble Space Telescope (HST) is an orbiting astronomical observatory operating from the near-infrared into the ultraviolet. Launched in 1990 and scheduled to operate through 2010, HST carries and has carried a wide variety of instruments producing imaging, spectrographic, astrometric, and photometric data through both pointed and parallel observing programs. MAST is the primary archive and distribution center for HST data, distributing science, calibration, and engineering data to HST users and the astronomical community at large. Over 100 000 observations of more than 20 000 targets are available for retrieval from the Archive.
The International Ultraviolet Explorer (IUE) performed spectrophotometry at high (0.1-0.3 Å) and low (6-7 Å) resolution between 1150 Å and 3200 Å. The data cover a dynamic range of approximately 17 astronomical magnitudes: -2 to 10 for high dispersion; -2 and 14.9 for low dispersion. Over 104,000 ultraviolet spectra were obtained with IUE between January 26, 1978, and September 30, 1996.
Launched in 2009, the Kepler Mission is surveying a region of our galaxy to determine what fraction of stars
in our galaxy have planets and measure the size distribution of those exoplanets.
Although Kepler completed its primary mission to determine the fraction of stars that have planets in 2013,
it is continuing the search, using a more limited survey mode, under the new name K2.
This service is the main Kepler data search.
This interface joins the Kepler Target Catalog (KTC) with other tables to allow users to access the Kepler data archive. Observed Kepler targets are included with their associated data set names. Since most of the Kepler light curve data is still proprietary, public data can be found by searching for release dates earlier than todays date.
The KIC, or Kepler Input Catalog, is the primary source of information about objects observed as part of the ground-based Kepler Spectral Classification Program (SCP) in preparation for the selection of Kepler PI and GO targets. The KIC lists objects down to 21st magnitude, but it is not complete to this limit. Light from only about 1/3 of these 14 million objects falls on the Kepler CCD detector. A small number of the KIC objects are calibration objects distributed across the sky.
