ESI Mar 2007 spectra page

This page shows some preliminary results from the Keck ESI run of 16 March 2007. The observers were Wal Sargent, Jason Prochaska, Daniel Jay Beeler and Bryan Penprase, looking for metallicity in SDSS quasar DLA systems. The data were reduced using the JXPs IDL XSpec routines, by JXP. A total of 11 quasars were observed, and the results are presented below

Detailed results from the analysis are below.
