Analysis of the Ly{alpha} forest at z=0-5. V.
Listed in IVOA Registry (Virtual Observatory)
In 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).
Description
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.
