J/PASP/116/622      SDSS damped Lyα survey: DR1        (Prochaska+, 2004)

The Sloan Digital Sky Survey damped Lyα survey: Data Release 1. Prochaska J.X., Herbert-Fort S. <Publ. Astron. Soc. Pac., 116, 622-633 (2004)> =2004PASP..116..622P
ADC_Keywords: QSOs ; Redshifts Abstract: We present the results from an automated search for damped Lyα (DLA) systems in the quasar spectra of Data Release 1 from the Sloan Digital Sky Survey (SDSS-DR1). At z∼2.5, this homogeneous data set has greater statistical significance than the previous two decades of research. We derive a statistical sample of 71 DLA systems (>50 previously unpublished) at z>2.1 and measure HI column densities directly from the SDSS spectra. File Summary:
