What does HSC mean in UNCLASSIFIED
HSC stands for Hubble Source Catalog, a comprehensive astronomical catalog containing information on a vast number of celestial objects observed by the Hubble Space Telescope (HST). The HSC serves as a valuable resource for astronomers and researchers studying various aspects of the universe.
HSC meaning in Unclassified in Miscellaneous
HSC mostly used in an acronym Unclassified in Category Miscellaneous that means Hubble Source Catalog
Shorthand: HSC,
Full Form: Hubble Source Catalog
For more information of "Hubble Source Catalog", see the section below.
Purpose
The main purpose of the HSC is to provide researchers with a standardized and uniform data set of Hubble Space Telescope observations. It includes detailed information on objects such as galaxies, stars, nebulae, and other astronomical sources. The catalog enables astronomers to:
- Conduct statistical studies on galaxy evolution, star formation, and the properties of extragalactic objects.
- Identify and classify new celestial objects, such as quasars, supernovae, and active galactic nuclei.
- Study the morphology and structure of galaxies, including their sizes, shapes, and internal features.
- Investigate the physical properties of stars, including their temperatures, masses, and spectral types.
Content
The HSC contains data from various HST instruments, including the Wide Field and Planetary Camera 2 (WFPC2), the Advanced Camera for Surveys (ACS), and the Wide Field Camera 3 (WFC3). The catalog includes:
- Object coordinates: Positions of celestial objects with high precision.
- Photometric measurements: Brightness and colors of objects in different wavelength bands.
- Morphological measurements: Structural parameters such as sizes, shapes, and asymmetry.
- Spectroscopic measurements: Data on the chemical composition, kinematics, and physical conditions of objects.
Accessibility
The HSC is publicly available online through the Mikulski Archive for Space Telescopes (MAST). Researchers can access the catalog data through the MAST Portal and utilize it for their scientific investigations. The HSC is regularly updated with new HST observations, ensuring that researchers have access to the most current and comprehensive information.
Essential Questions and Answers on Hubble Source Catalog in "MISCELLANEOUS»UNFILED"
What is the Hubble Source Catalog (HSC)?
The Hubble Source Catalog (HSC) is a collection of astronomical data gathered from observations made by the Hubble Space Telescope (HST). The HSC contains information on millions of celestial objects, including galaxies, stars, and quasars.
What types of data does the HSC provide?
The HSC provides data on various astronomical parameters, including:
- Object position and shape
