SDSS DLA Survey

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.
