DEEP2 Data Release 2
The fourth data release (DR4) for the DEEP2 galaxy redshift survey is now available, including the previously released data from DR1, DR2, and DR3. Documentation and download instructions for DR4 are available here.



The DEEP2 project is a redshift survey of 50,000 distant galaxies utilizing the DEIMOS spectrograph on the Keck II telescope. Data release 2 (DR2) is the second public data release for the survey and includes redshift and imaging catalogs in addition to 1-d and 2-d spectra for approximately 75% of the survey. Note that this release includes DR1, as a subset. In addition to including the 70 slitmasks released as part of DR1, data release 2 spans 291 DEIMOS slitmasks, which were observed during the 2002 - 2005 DEEP2 observing seasons (data collected August 2002 - September 2005). The slitmasks included in this release cover three of the four DEEP2 fields as shown in this sky coverage map.


The DR2 Data Products Page provides details regarding the contents of data release 2 and links to all public data products available for download. The FAQ page may help in answering common questions regarding DR2. Please refer to the credits page for a list of our sources of funding, participating institutions, and how to acknowledge the use of DEEP2 data in publications.
