cds-question@unistra.frspectroscopyultraviolet-astronomyearly-type-starsWe have selected spectra of 232 stars from the IUE archives for inclusion in an atlas intended for various uses but tailored especially for the study of stellar winds. The atlas covers the range in spectral types from O3 to F8. The full atlas covers the reduced and normalized high resolution spectra from the IUE long- and short-wavelength spectrographs. Here we discuss the selection of the stars and the data reduction, and we present in velocity units the profiles of lines formed in the stellar winds. The selected lines cover a wide range of ionizations, allowing a comparison of the profiles from different ions in the wind of each star and a comparison of the different wind lines as a function of spectral type and luminosity. We also present the basic data on the program stars to facilitate study of the dependence of wind features on stellar parameters such as luminosity, temperature, escape velocity, and v sin i. We provide an overview of the characteristic behavior of the wind lines in the H-R diagram. The complete spectra are available in digital form through the NASA Astrophysics Data System (ADS). We offer a description of the electronic database that is available through the ADS and guidelines for obtaining access to that database.1994ApJS...95..163Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/95/163CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/95/163https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/95/163http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/95/163https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/95/163https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/95/163http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/95/163GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/95/163/table3 (Basic properties of atlas stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/95/163/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/95/163/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/95/163/table3?GETtext/xml+votable180.050000true161.187917-59.5650.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/95/163?format=asciiUVdefaultJ/ApJS/95/163/table3Basic properties of atlas starsHDHenry Draper Catalog numbermeta.idintm_HDHD Catalog componentmeta.code.multipcharBinIndication of binarity (2)meta.codecharNum[1/232] Star numbermeta.id;meta.mainintprimaryrecnoRecord number assigned by the VizieR team.
