cds-question@unistra.frquasarsredshiftedspectroscopyultraviolet-astronomyWe measure the distribution of carbon in the intergalactic medium as a function of redshift z and overdensity {delta}. Using a hydrodynamical simulation to link the H I absorption to the density and temperature of the absorbing gas, and a model for the UV background radiation, we convert ratios of C IV to H I pixel optical depths into carbon abundances. For the median metallicity this technique was described and tested in Paper I (Aguirre et al., 2002ApJ...576....1A) of this series. Here we generalize it to reconstruct the full probability distribution of the carbon abundance and apply it to 19 high-quality quasar absorption spectra.2003ApJ...596..768Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/596/768CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/596/768https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/596/768http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/596/768https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/596/768https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/596/768http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/596/768GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/596/768/table1 (Observed quasars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/596/768/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/596/768/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/596/768/table1?GETtext/xml+votable180.050000true165.855375-26.7543610.0055555555555555566/5563 5610 8912 11498 16656 18642 25120 25285 34485 34570 35496 35595 35627 36130 43903 45526 46418 47007 48610https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/596/768?format=asciiUVOpticaldefaultJ/ApJ/596/768/table1Observed quasarsLambdaminMinimum wavelength0.1nmfloatrecnoRecord number assigned by the VizieR team.
