资源简介：
A survey of the low-redshift intergalactic medium (IGM) has been performed by Danforth et al. (2015). Using HST COS spectra of 82 UV-bright AGN, several thousand absorption lines are identified from 2,610 distinct redshift systems at z < 0.723. The spectral features were selected and measured using a semi-automated analysis to minimize bias in line identification. For each of the 82 sightlines, a coadded, continuum-fitted spectrum is provided in FITS format. Two catalogs for each sightline are presented: one catalog lists the identified spectral features sorted by wavelength, while another lists the absorption features associated with IGM systems sorted by redshift.
