The Sloan Digital Sky Survey (SDSS) will provide the data to support detailed investigations of the distribution of luminous and non-luminous matter in the Universe: a photometrically and astrometrically calibrated digital imaging survey of π steradians above about Galactic latitude 30 • in five broad optical bands to a depth of g ′ ∼ 23 m , and a(More)
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDSS-II. It includes 11663 deg 2 of imaging data, with most of the ∼ 2000 deg 2 increment over the previous data release lying in regions of low Galactic latitude. The catalog(More)

This paper describes the Sixth Data Release of the Sloan Digital Sky Survey. With this data release, the imaging of the northern Galactic cap is now complete. The survey contains images and parameters of roughly 287 million objects over 9583 deg 2 , including scans over a large range of Galactic latitudes and longitudes. The survey also includes 1.27(More)
The Sloan Digital Sky Survey has validated and made publicly available its First Data Release. This consists of 2099 square degrees of five-band (u g r i z) imaging data, 186,240 spectra of galaxies, quasars, stars and calibrating blank sky patches selected over 1360 square degrees of this area, and tables of measured parameters from these data. The imaging(More)

This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band photometric data for 180 million objects selected over 6670 deg 2 , and 673,280 spectra of galaxies, quasars, and stars selected from 4783 deg 2 of that imaging data using the(More)
An architecture-flow diagram extension to the Teamwork dataflow diagramming tool is described. The extension, called TWKAFD, manages FIG format files representing architecture-flow and interconnect diagrams and invokes the X Window version of FIG to let designers graphically edit them. Designers edit the diagrams using simple drawing primitives instead of(More)
