	Astrophysics Data System - Wikipedia, the free encyclopedia
		Data in the preprint archive is updated daily from the arXiv, the main repository of physics and astronomy preprints.
		The scripts are designed to be as platform independent as possible, given the need to facilitate mirroring on different systems around the world, although the growing dominance of Linux as the operating system of choice within astronomy has led to increasing optimisation of the scripts for installation on this platform.
		In the cases of the major journals of astronomy (Astrophysical Journal, Astronomical Journal, Astronomy and Astrophysics, Publications of the Astronomical Society of the Pacific and the Monthly Notices of the Royal Astronomical Society), coverage is complete, with all issues indexed from number 1 to the present.

	The SDSS Data System and Data Products
		To ease the offline processing, the data from a single CCD are divided into frames of 1362 rows each (one half the separation between CCD centers) and recorded in a staggered fashion such that frames from the 5 filters for a given piece of the sky are written sequentially on tape.
		Data that are crucial for the calibration of the spectra and their correlation to the photometric survey will be written along with the spectra.
		The focus system is discussed in some detail in Chapter 4; here it need only be noted that only the fitting parameters for the focus images, which are like the astrometric images, need to be stored, though we may store postage stamps as well to allow analysis of the performance of the focusing system.

		Astrophysics Data System is a NASA funded project tasked with providing access to astronomical information through the World Wide Web (WWW).
		Coverage for most of these publications goes back to 1975, but as more data is converted in digital form from hardcopy, coverage for most astronomy journals will be extended back to volume 1.

		The NASA Astrophysics Data System: Sociology, Bibliometrics, and Impac
		The NASA Astrophysics Data System (ADS), along with astronomy's journals and data centers, has developed a distributed on-line digital library which has become the dominant means by which astronomers search, access and read their technical literature.
		By combining data from the text, citation, and reference databases with data from the ADS readership logs we have been able to create Second Order Bibliometric Operators, a customizable class of collaborative filters which permits substantially improved accuracy in literature queries.

	Astronomy/Astrophysics Resources
		The Planetary Data System (PDS) archives and distributes digital data from past and present NASA planetary missions, astronomical observations, and laboratory measurements.
		The Data Centre is part of the Cambridge Astronomy Survey Unit and houses a good selection of data from the UK's ground based telescopes as well as a number of catalogues.
		They are in general accord with the recommendations of the International Astronomical Union and are consistent with the IAU (1976) system of astronomical constants apart from minor modifications introduced to permit a better fit to observations; in particular, dynamical time-scales and the standard reference system of J2000.0 are used where appropiate.

	The Astrophysics Data System and WWW (Site not responding. Last check: 2007-10-21)
		In an environment of distributed data and interdisciplinary science, it is essential that data be accomplanied by a searchable database of metadata.
		Therefore, the developer or data provider does the same development of the metadata and data base organization to provide data regardless of the interface to be used.
		Alternatively if the data or service is to be provided to the community in concert with other data and services, the ADS infrastructure, augmented with clear documentation available through the Xmosaic interface, may be a wise choice.

		The process that takes the system from A to B is called absorption and is the reason why the intensity of radiation is attenuated when it passes through matter.
		The process that takes the system from B to A is called stimulated emission--the interaction of radiation with particles leads to the emission of an additional photon.
		P. Armitage, Department of Astrophysical and Planetary Sciences, University of Colorado, provides lecture notes (in PDF format) for astrophysics 1 and astrophysics 2 courses.

	[No title]
		Systems as diverse as the early universe, the interstellar medium, red giant stars, and supernova explosions are currently the focus of intense studies utilizing sophisticated computer models -- models which require large quantities of nuclear data as input.
		The rates are derived from laboratory measurements of cross sections of relevant reactions -- primarily fusion, transfer, and decay reactions -- convoluted with a thermal (Maxwell-Boltzmann) relative velocity distribution; the released energies of the relevant reactions (Q-values) are derived from measurements and calculations of masses.
		An overview of the current status of nuclear data for nuclear astrophysics is given in M.S. Smith, Nuclear Physics A718 (2003) 339c.
