cds-question@unistra.frastronomical-modelsextinctionWe study the IR-through-UV wavelength dependence of 328 Galactic interstellar extinction curves affecting normal, near-main-sequence B and late O stars. We derive the curves using a new technique that employs stellar atmosphere models in lieu of unreddened "standard" stars. Under ideal conditions, this technique is capable of virtually eliminating spectral mismatch errors in the curves. In general, it lends itself to a quantitative assessment of the errors and enables a rigorous testing of the significance of relationships between various curve parameters, regardless of whether their uncertainties are correlated.2007ApJ...663..320Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/663/320CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/663/320https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/663/320http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/663/320https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/663/320https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/663/320http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/663/320GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/663/320/stars (Survey stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/663/320/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/663/320/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/663/320/stars?GETtext/xml+votable180.050000true2.904778358.21182970.0055555555555555565/3869 6/461 859 1039 1044 1055 1060 1102 1124 1134 1293 1329 1431 1460 1539 1550 1777 1799 1814 2909 2940 3004 3057 3244 3256 3257 3258 3263 3283 3301 3312 3384 3585 3600 3608 3796 3798 3842 13214 13289 14015 14173 14213 14245 14249 14251 14273 14305 14311 14368 14641 14643 14645 14646 14653 14655 14690 14737 14741 15369 15372 15399 15406 15481 15484 15485 15486 15519 15611 15625 15663 15682 15683 15686 15687 15689 15692 15842 19009 21428 21438 21439 21483 21638 21644 22033 22208 22240 22243 22246 22249 22253 22258 22264 22805 22854 22855 23410 23488 23637 23644 23647 23982 24228 24230 24325 24331 24333 24463 24513 24552 28759 28890 28891 28916 29040 29095 29138 29463 29522 29876 30287 30334 30356 30366 30709 30818 31121 31169 37145 37333 37334 37871 37887 37897 37938 38016 38018 38024 39174 39243 39272 39281 39334 39774 39796 41129 41134 41650 41651 41660 41692 42226 42383 42394 42395 42503 42947 42959 42967 42977 42980 42981 42985 42989 42994 43027 43030 43033 43036 43040 44366 44378 45105 47656 47739 47742https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/663/320?format=asciidefaultJ/ApJ/663/320/starsSurvey starsrecnoRecord number assigned by the VizieR team.
