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.


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.
