DEEP2 Galaxy Redshift Survey

 

The DEEP2 DR4 redshift catalog includes 52,989 entries, with 36 fields (or tags) per entry. A description of each tag is given in the "ztags" primer. We package the catalog as a BINARY TABLE in a standard FITS file, but also provide a version formatted as a space-deliminated ASCII table. For any publication making use of data included in DR4, please refer here for the relevant references and acknowledgments:

The DEEP2 DR4 Redshift Catalog

Note that these redshift catalogs include all spectroscopic targets regardless of whether an accurate redshift was measured; only galaxies with redshift quality (ZQUALITY) greater than or equal to 3 should be treated as having a reliable redshift measurement (objects identified as stars are given ZQUALITY of -1). Also, be sure to note that while there are 52,989 entries in the redshift catalog, some objects were observed multiple times (to test redshift accuracy, etc.) and the redshift catalog contains 50,319 unique objects. In addition to the full catalog, here we provide a trimmed, unique redshift catalog which removes duplicated objects (keeping entries with higher redshift quality where appropriate):
