cds-question@unistra.frquasarsspectroscopyIn Paper III (Bechtlod et al., 2002, Cat. <J/ApJS/140/143>) of our series, "A Uniform Analysis of the Ly{alpha} Forest at z=0-5", we presented a set of 270 quasar spectra from the archives of the Faint Object Spectrograph (FOS) on the Hubble Space Telescope (HST). A total of 151 of these spectra, yielding 906 lines, are suitable for using the proximity effect signature to measure J({nu}_0_), the mean intensity of the hydrogen-ionizing background radiation field, at low redshift.2002ApJ...571..665Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/571/665CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/140/143 : Analysis of the Ly{alpha} forest at z=0-5.
