Beginning of ReadMe : J/PASP/118/1077 Metal-strong damped Lyalpha systems (Herbert-Fort+, 2006) ================================================================================ The metal-strong damped Lyalpha systems. Herbert-Fort S., Prochaska J.X., Dessauges-Zavadsky M., Ellison S.L., Howk J.C., Wolfe A.M., Prochter G.E. <Publ. Astron. Soc. Pac., 118, 1077-1097 (2006)> =2006PASP..118.1077H ================================================================================ ADC_Keywords: QSOs ; Redshifts ; Spectroscopy Abstract: We have identified a metal-strong [logN(Zn+)>=13.15 or logN(Si^+^)>=15.95] damped Lyalpha (MSDLA) population from an automated quasar (QSO) absorber search in the Sloan Digital Sky Survey (SDSS) Data Release 3 quasar sample and find that MSDLAs comprise >>5% of the entire DLA population with z_abs_>=2.2 found in QSO sight lines with r<19.5. We have also acquired 27 Keck ESI (Echellete Spectrograph and Imager) follow-up spectra of metal strong candidates in order to evaluate our automated technique and examine the MSDLA candidates at higher resolution.
