VizieR Online Data Catalog: C IV BAL troughs properties in quasars (Filiz+, 2014)
Abstract
We utilize spectroscopic observations from the Sloan Digital Sky Survey-I/II (hereafter SDSS, York et al. 2000AJ....120.1579Y) and the Baryon Oscillation Spectroscopic Survey of SDSS-III (hereafter BOSS; Eisenstein et al. 2011AJ....142...72E; Dawson et al. 2013AJ....145...10D). We select a sample of quasars for this study from these 2005 targets that were observed by SDSS between MJD 51,602 (2000 February 28) and 54,557 (2008 January 4) and by BOSS between MJD 55,176 (2009 December 11) and 56,455 (2013 June 12). Observation start dates correspond to completion of hardware commissioning for both SDSS and BOSS; post-commissioning observations have the most reliable spectral calibration.
