As part of SDSS-II, SEGUE utilizes the 2.5 meter SDSS telescope on Apache Point in New Mexico to obtain ugriz imaging data at moderate to low Galactic latitude (|b| < 35 degrees) and spectroscopy of selected stellar targets over the wavelength range 3,800 Å ~ 9,200 Å.

SEGUE will ultimately acquire:

• 3,500 square degrees of new imaging data
• Spectra of 240,000 stars

The large statistical sample of stars and volume of the galaxy probed by SEGUE will be unmatched by any other survey for at least a decade.

Accessing the Data

• Getting Started – a guide to working with SEGUE data, including sample SQL queries.
• SkyServer – public access to SEGUE and SDSS-I and -II data via the Catalog Archive Server (CAS).
• CAS – CAS access for astronomers.
• DAS – the Data Archive Server (DAS) contains FITS format files of SDSS and SEGUE data.

Survey Strategy and Algorithms

• Imaging
• Target Selection
• Spectroscopy

Survey Status

SEGUE began taking data in August of 2004, and will complete its targeted data set in 2008. The SDSS DR6 data release includes roughly half of the planned SEGUE imaging data, and nearly 100,000 spectra (~40% of planned targets).

• SEGUE sky coverage – imaging footprint and current observational status
• SEGUE plate list – spectroscopic plate data, with links to individual spectra
