The SDSS DLA Survey

These pages give tables and figures of DLA identified in the SDSS. We also provide the papers of reference for this material.


Data Products

  • Published SDSS DR3 Table: This table gives the DLA published in PHW05. Unfortunately, although we introduced an algorithm to avoid having the OVI/Lyb QSO emission line from biasing our g(z), the algorithm was not properly implemented for the results in this paper. The overall effect is an increase of ~10% in f(N) at all redshifts.
  • Corrected SDSS DR3 Table: This table gives the correct DR3 results, corrected for the error described above.
  • Proximate DLA
  • DR5 DLA: This table gives the full set of DLA from the DR5 which now includes a total of 739 DLAs in the statistical sample and over 1000 DLAs total. It is, of course, inclusive with the DR3. The key findings were just published in Prochaska & Wolfe (2009).
    My special thanks to Michael Murphy (Swinburne) who identified mistakes in the a previous presentation of these data.
