What is SDSS SkyServer?
The Sloan Digital Sky Survey, or SDSS, is an international collaboration of scientists gathering data from two telescopes in North and South America to build the most detailed Three-Dimensional Imagery of the Universe ever made.
How do I access SDSS data?
You can view SDSS images online for any object or sky position in the survey area, and download images of SDSS fields as FITS files. Since some stars were targeted for APOGEE infrared spectroscopy using 2MASS survey data, we also offer access to 2MASS images through the Navigate tool (click on the 2MASS button).
Where is the Sloan Digital Sky Survey?
Apache Point Observatory
The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States.
What is a sky Server?
The SkyServer provides Internet access to the public Sloan Digital Sky Survey (SDSS) data for both astronomers and for science education. The SDSS is a 5-year survey of the Northern sky (10,000 square degrees) to about 1/2 arcsecond resolution using a modern ground-based telescope [SDSS].
What does the acronym SDSS stand for?
SDSS
Acronym | Definition |
---|---|
SDSS | Stability and Ductility of Steel Structures |
SDSS | Standard Defence Supply System (Australia) |
SDSS | Super Duplex Stainless Steel |
SDSS | Server Display and Script Services |
What is Digital Sky Survey?
The Digitized Sky Survey (DSS) is a ground-based imaging survey of the entire sky in several colors. The survey, performed with Palomar and UK Schmidt telescopes, produced photographic plates that were later digitized at the Space Telescope Science Institute (STScI) to produce the Hubble Guide Stars Catalog (GSC).
Where is the SDSS telescope?
The SDSS uses a dedicated 2.5-m f/5 modified Ritchey-Chrétien altitude-azimuth mount telescope located at Apache Point Observatory, in south east New Mexico in the south west of the United States (Latitude 32° 46′ 49.30″ N, Longitude 105° 49′ 13.50″ W, Elevation 2788m).
What is the purpose of the SDSS?
The SDSS will measure the distribution of nearby galaxies, allowing astronomers to compare them with more distant galaxies now being seen by the new instruments like the Hubble Space Telescope and the Keck Telescope.
Where can SDS be obtained?
To obtain SDS, get them from the manufacturer.
- They may be sent with the chemical order (paper copy or e-mail attachment).
- Otherwise, go to the manufacturer’s website and download it or request a copy.
How many OSHA mandated sections are there on each SDS?
16-section
The information contained in the SDS is largely the same as the MSDS, except now the SDSs are required to be presented in a consistent user-friendly, 16-section format.
How does the SDSS work?
The SDSS takes imaging data in long, narrow “stripes”, 2.5 degrees wide. Part of the processing of SDSS images is to select some objects as targets for follow-up spectroscopy. The SDSS then collects spectra later. Most spectra were collected using the original SDSS-I/-II spectrograph.
Where can I find SDSS data release 14?
Data Release 12, Data Release 13, and Data Release 14 are still available on this website, and prior data releases are available from www.sdss3.org (for DR8 through DR10) or classic.sdss.org (for DR1 through DR7). If you use public SDSS data in your paper, please see our guide on how to cite the SDSS.
Where can I find old SDSS survey data?
It and Data Releases 1-7 are fully intact and can now be found on the “SDSS Classic” website. We continue to maintain the SDSS3.org website. Data Releases 8-10 can be found there. The SDSS began regular survey operations in 2000, after a decade of design and construction.
What is the history of the SDSS?
The SDSS began regular survey operations in 2000, after a decade of design and construction. It has progressed through several phases, SDSS-I (2000-2005), SDSS-II (2005-2008), SDSS-III (2008-2014), and SDSS-IV (2014-2020). Each of these phases has involved multiple surveys with interlocking science goals.
What online data access tools does the SDSS offer?
The SDSS offers several different online data access tools, each suited to a particular need: Flexible advanced SQL-based interface to the CAS, for all data releases (quick registration required). To select data from DR15, choose DR15 as the query context.
