cds-question@unistra.frquasarsredshiftedvisible-astronomysloan-photometryWe present a catalog of 224 broad absorption line quasars (BALQSOs) from the Sloan Digital Sky Survey's Early Data Release Quasar Catalog, (Schneider et al., 2002, Cat. <J/AJ/123/567>) including a relatively complete and homogeneous subsample of 131 BALQSOs. Since the identification of BALQSOs is subject to considerable systematic uncertainties, we attempt to create a complete sample of SDSS BALQSOs by combining the results of two automated selection algorithms and a by-eye classification scheme. One of these automated algorithms finds broad absorption line troughs by comparing with a composite quasar spectrum. We present the details of this algorithm and compare this method with one that uses a power-law fit to the continuum. The BALQSOs in our sample are further classified as high-ionization BALQSOs (HiBALs), low-ionization BALQSOs (LoBALs), and BALQSOs with excited iron absorption features (FeLoBALs); composite spectra of each type are presented. We further present a study of the properties of the BALQSOs in terms of the balnicity distribution, which rises with decreasing balnicity. This distribution of balnicities suggests that the fraction of quasars with intrinsic outflows may be significantly underestimated. The balnicity index defined by Weymann et al. (1991ApJ...373...23W) amounts to a sort of equivalent width: a quasar is declared to be a BAL when its balnicity index is >=0.2003AJ....125.1711Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/125/1711CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/123/567 : SDSS quasar catalog (Schneider+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/125/1711https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/125/1711http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/125/1711https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/125/1711https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/125/1711http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/125/1711GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/125/1711/table1 (SDSS EDR BALQSO Catalog: Objects with 1.7<=z<=4.2)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/125/1711/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/125/1711/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/125/1711/table1?GETtext/xml+votable180.050000true0.2370417-1.06938890.005555555555555556Cone search capability for table J/AJ/125/1711/table2 (Supplementary SDSS EDR BALQSO Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/125/1711/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/125/1711/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/125/1711/table2?GETtext/xml+votable180.050000true5.92908331.04522220.0055555555555555565/6569 6/0 2 8192 10062-10063 10073 10084 10086 10092-10093 10098-10099 10105 10107 10179-10181 10190-10192 10194 10200 10202 10212 10214 10217 10221-10222 10226 11588 17405 17407 17661 17663 17743 17746 17749 17751 17754-17757 17763-17764 17766-17767 17772 17778 17806 17813-17814 17816-17817 17828-17829 17831-17832 17836 17840 17857 17982 17997-17998 18011-18013 18019-18021 18025-18029 18032 18069 18077 18081 18085-18086 18092 18097-18098 18113 18177-18178 18767 18772 18774 18780-18782 18795 23182-23183 23187-23188 23192-23193 23203 23205 23207 23211 23216 25919 25939 25941 25943-25944 25948 25956 25959-25960 25964 25968 26007 26010-26011 26019 26023 26173 26193 26196 26200 26202 26204 26206 26212-26214 26217 26221 26255 26258-26260 26263 26267 26270 26275 26280-26281 26283 26285-26286 26305 26368 26962-26964 26966-26967 26970 26981 26983 26988 26992 27021 27025 27028 27030-27031 27034-27035 27043 27045-27046 27048 27052-27053 27074 27197 27220-27221 27223 27226 27233 27241 27285 31375 31384-31385 31399 45055https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/125/1711?format=asciiOpticaldefaultJ/AJ/125/1711/table1SDSS EDR BALQSO Catalog: Objects with 1.7<=z<=4.2recnoRecord number assigned by the VizieR team.
