ESI Mar 2008 spectra page


This page shows some preliminary results from the Keck ESI run of 08 and 09 May 2008. The observers were Wal Sargent, Jason Prochaska, 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 34 quasars were observed, with detections of 35 DLA systems and the results are presented below.
Detailed results from the analysis are below.
