As part of SDSS-II, SEGUE utilized 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 ultimately acquired:
- Over 3,200 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
Catalog Archive Server (CAS).
- CAS – CAS access for
DAS – the Data Archive Server (DAS) contains FITS format
files of SDSS and SEGUE data.
Survey Strategy and Algorithms
SEGUE began taking data in August of 2004, and completed its
targeted data set in 2008. The
SDSS DR7 data release was the final release.
