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 WARNING: The following are superseded (for now)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.
