cds-question@unistra.frob-starsultraviolet-photometryvisible-astronomybroad-band-photometryinfrared-photometryWe have applied the method of investigating extinction curves using statistically meaningful samples that was proposed by us 25 years ago. The extensive data sets of the ANS (Astronomical Netherlands Satellite) and 2MASS (Two Micron All Sky Survey) were used, together with UBV photometry to create average extinction curves for samples of OB stars. Our results demonstrate that in the vast majority of cases the extinction curves are very close to the mean galactic extinction curve. Only a few objects were found to be obviously discrepant from the average. The latter phenomenon may be related to nitrogen chemistry in translucent interstellar clouds.2012AN....333...60Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/333/60CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/97 : ANS UV Catalogue of Point Sources (Wesselius+ 1982)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/333/60https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/333/60http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/333/60https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/333/60https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/333/60http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/333/60GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/333/60/OBstars (Colour indices of OB stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/333/60/OBstars?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/333/60/OBstars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/333/60/OBstars?GETtext/xml+votable180.050000true30.625531455.62399330.0055555555555555565/3657 6/257 903 1040 1060 1102 1115 1209 1293 1297 1299 1335 1342 1429-1430 1555 1848 1929 1960 2409 2873 2947 2996 3040 3050 3057-3058 3060 3137 3144 3244-3245 3254 3256 3281 3283 3297 3301-3302 3312 3337 3464 3585 3589 3599-3600 3602 3608 3626 3638 3643 3648 3653 3718 3816 5506 6558 6578 6891 7149 7240 9478 9680 10731 12425 12766 13025 13040 13234 13255 13268 13276-13277 13289 13306 13535 13554 13557 13566 13703 13748 13751 13967 14003-14004 14008 14015 14038 14042 14047 14071-14072 14187 14197 14207 14223 14246-14247 14253 14264 14279-14280 14282-14283 14302-14304 14325-14326 14346-14347 14357 14365 14368-14369 14381 14412 14425-14426 14443 14457 14495 14552 14601 14604 14622 14642 14645-14647 14651 14653 14655 14658 14665 14679 14683 14689-14690 14740 14783 14798 14802 14805 14927 14945 15368-15369 15372-15374 15376 15385 15392 15394 15452 15455 15476 15479 15493 15510-15511 15525 15577 15625 15653-15654 15656 15660 15683 15686 15689 15692 15703 15713 15768 16131 16304 19676 20546 20613 20753 20756 20760 20804 20900 20974 21227 21233 21303 21324 21430 21432 21434-21436 21439 21447 21450 21456 21465 21479 21482 21515 21518-21519 21529-21530 21545 21565 21567 21638 21644 21646 21655 21661 21685 21879 21997 22039-22040 22053 22058 22088 22125 22164 22207 22209 22211 22223 22235-22236 22243 22246 22249 22252-22253 22579 22615 22805 22836-22837 22845 22850 22854 22858-22859 22861-22862 22881 22888 22893 22895 22898 22904 22907 22994 23281 23483 23628 23632 23637 23644 23647 23695 23714 23738 23764 23779 23800 23807 23936 23969 23976 23981 23984 23993 23996 23998 24000 24019 24085 24151 24180 24238 24325 24328 24340 24364 24366 24376 24381 24463 24469 24489 24496 24511 24546 24552 24555 25988 26929 28833 28866 28890 28907 28968 28996 29097 29100 29134 29159 29164 29176 29179 29182 29318 29320 29457 29520 29527 29529 29534-29535 29621 29876 30217 30281 30440 30477 30492 30573 30627 30630 30632 30642-30643 30709 31063 31759 32052 32109 32120 32126 32216 32576 32580 32953 34041 37145 37150 37231 37247 37254 37327 37334 37487 37693 37716 37750 37764 37776 37782 37802 37816 37827 37854 37864-37865 37883 37886 37896 37899 37903 37905-37906 37927 37932 38051 38248 38406 38409 38424 38452 38562 38597 38925 38996 39075 39179 39181 39187 39193-39194 39202 39217-39218 39227 39243 39252 39254 39265 39267 39297 39304 39311 39337 39341 39369 39375 39402 39539 39645 39679 39696 39699 39704 39715-39716 39720 39730 39732 39739 39742 39806 39828 39832 39861 39863 39868-39869 39905 39907 39930 39946 39970 40584 40616 40621 40651 41171 41557 41598-41599 41606-41607 41653 41686 41705 41747 41903 41973 42195 42220 42237 42383 42394 42405 42407 42416 42428 42441 42483 42595 42633 42672 42924 42932 42948 42959 43011 43018 43038 43041 43062 43067 43183 43211 43307 43365 43383 43397 43414 43521 43538 44086 44306 44312 44316 44366 44378 44385-44386 44469 47761 47855 47916 48072 48199https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/333/60?format=asciiUVOpticalInfrareddefaultJ/AN/333/60/OBstarsColour indices of OB starsrecnoRecord number assigned by the VizieR team.
