Summary Tables for the DR5 SDSS-DLA Survey

This page provides a few summary tables from analysis of the DLA in the SDSS DR5. If you don't find what you are looking for, please request more. WARNING: The following are superseded (for now) by the results published in Prochaska & Wolfe 2009.


HERE is an ASCII table of the f(N_HI) values with arbitrary binning.


The following table summarizes fits to the f(N_HI) distribution for the DR5 DLA. This is otherwise identical to Table 6 in the DR3 paper.

The following table summarizes the f(N_HI) values, l(X) values and Omega(DLA) values for the SDSS-DR5 DLA. This is otherwise identical to Table 9 of the DR3 paper.
