Third data release: DEEP2 Galaxy Redshift Survey
The following is from Sandy Faber. There's also a press release at:
http://press.ucsc.edu/text.asp?pid=1615 We take pleasure in announcing the THIRD DATA RELEASE (DR3) from the recently completed DEEP2 GALAXY REDSHIFT SURVEY, which provides the most detailed spectroscopic census of the Universe at z ~ 1 to date. The survey targeted ~50,000 distant galaxies in four fields in the redshift range 0 z 1.4 utilizing the DEIMOS multi-object spectrograph on the Keck II telescope. DR3 is the third public data release for the survey. Products include: * Fully reduced extracted 1-d extracted spectra from roughly 400 slitmasks. * Two-d spectral images, which provide unique spatial information on gas kinematics and extent along the slit. * Current redshift and photometric catalogs for all spectroscopically targeted objects. (Original BRI CFHT images are available on request.) * 100 additional slitmasks observed from May 2003 to July 2005 and never released before. * The first release of roughly 10,000 DEEP2 spectra from the Extended Groth Strip (EGS), which is the location of the AEGIS multiwavelength survey. Unlike other DEEP2 fields, galaxies of all colors were targeted in the EGS, including objects with expected z 0.7. All data are available at the URL: http://deep.berkeley.edu/DR3 There you will find details regarding the contents of DR3 and links to all public data products available for download. The FAQ page answers the most common questions regarding DR3. Please also refer to the credits page on this website for a list of our sources of funding, participating institutions, and how to acknowledge the use of DEEP2 data in publications. WITH DR3, ALL ORIGINAL DATA PRODUCTS FROM THE DEEP2 SURVEY ARE NOW PUBLIC. Future data releases will feature improved redshift catalogs and derived data products (e.g., linewidths or EWs). The first release of AEGIS MULTIWAVELENGTH DATA is also expected shortly. DEIMOS spectroscopy is continuing in EGS through a Keck Large Multi-year Approved Program (LMAP). The extension, called DEEP3, will approximately triple the number of DEIMOS redshifts available in EGS (to 18,000), target special populations such as MIPS, Chandra and radio sources, deepen the survey to R = 25.5 mag, and increase the quality of environmental information available by nearly an order of magnitude. The timescale for completing DEEP3 is roughly four years. |
