cds-question@unistra.frinterstellar-mediumchemical-abundancesspectroscopyWe discuss several sets of TiII absorption-line data, which probe a variety of interstellar environments in our Galaxy and in the Magellanic Clouds. Comparisons of high-resolution [full width at half-maximum (FWHM)~1.3-1.5km/s] TiII spectra of Galactic targets with corresponding high-resolution spectra of NaI, KI and CaII reveal both similarities and differences in the detailed structure of the absorption-line profiles - reflecting component-to-component differences in the ionization and depletion behaviour of those species. Moderate-resolution (FWHM~3.4-4.5km/s) spectra of more heavily reddened Galactic stars provide more extensive information on the titanium depletion in colder, denser clouds - where more than 99.9 per cent of the Ti may be in the dust phase. Moderate-resolution (FWHM~4.5-8.7km/s) spectra of stars in the Magellanic Clouds suggest that the titanium depletion is generally much less severe in the Large and Small Magellanic Clouds than in our Galaxy [for a given N(Htot), E(B-V), or molecular fraction f(H2)]- providing additional evidence for differences in depletion patterns in those two lower-metallicity galaxies. We briefly discuss possible implications of these results for the interpretation of gas-phase abundances in quasi-stellar object absorption-line systems and of variations in the D/H ratio in the local Galactic interstellar medium.2010MNRAS.404.1321Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/404/1321CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/171/29 : UCSD/Keck damped Ly{alpha} abundance database (Prochaska+ 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/404/1321https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/404/1321http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/404/1321https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/404/1321https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/404/1321http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/404/1321GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/404/1321/tablea1 (Component structures for Galactic sight lines for which high-resolution (FWHM<2km/s) CaII spectra are available)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/404/1321/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/404/1321/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/404/1321/tablea1?GETtext/xml+votable180.050000true58.533006431.88363560.005555555555555556Cone search capability for table J/MNRAS/404/1321/tablea2 (*314 Galactic sight lines for which TiII data ({lambda}3383 equivalent widths and/or column density estimates) are available)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/404/1321/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/404/1321/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/404/1321/tablea2?GETtext/xml+votable180.050000true3.3089715.18359580.005555555555555556Cone search capability for table J/MNRAS/404/1321/tablea3 (QSOALS TiII column densities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/404/1321/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/404/1321/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/404/1321/tablea3?GETtext/xml+votable180.050000true1.33423755.40299110.0055555555555555566/2 8 252 463 472 474 771 1060 1196 1198 1293 1430 1539 1550 1558 1633 1766 1769 2172 2348 2409 2775 2884 3030 3060 3136 3430 4027 4140 4273 4279 4820 5263 5506 5780 6252 6403 6891 7240 7964 8490 8494 9252 9552 10061 10731 12400 12405 12415 13001 13268 13331 13480 13557 13721 13729 14008 14055 14082 14167 14305 14711 14777 14805 14824 14855 15368-15369 15375 15478-15479 15631 15663 15672 15745 15747 16269 16490 16798 17312 17314 17321-17322 17404 17749 17754 17777 17818 17833 18042 18081 18200 18366 18439 18447 18560 18712 18765 18772 18858 18928 19009 19202 19206 19287 19336 19402 19483 19676 19682 19757 20032 20107 20116 20516-20517 20613 20759 20764 20915 20975 21012 21180 21227-21228 21233 21365 21401 21438-21439 21515 21635 21647 21879 22039 22246 22258 22489 22517 22579 22615 22772 22787 22837 22845 22850 22854 22859 22862 22880 22884 22890 22911 22917 22994 23007 23016 23050 23360 23374 23483 23581 23637 23717 23979 24179 24370 25002 25016 25138 25245 25285 25659 25799 25935 25940 25976 25988 25993 26165 26196 26255 26276 26315 26614 26867 26879 26929 27002 27029-27030 27034 27037 27049 27333 27402 27498 27554 27577 27650 27739 27747 27841 28039 28042 28672 28687 28890 28915 28944 28968 29085 29089 29149 29162 29208 29513 29522 29537 29621 29809 29828 29876 29893 30356 30718 30722 30818 30925 31686 31696 31705 31710 31756 31929 32174 32793 33225 33652 34107 34202 34503 34878 34896 34914 35095 35786 36043 37231 37245 37333 37364 37584 37706 37717 37732 37777 37790 37865 37869 37900 37926 37930 37948 38016 39075 39170 39216 39240 39243 39252 39281 39327 39334 39374 39486 39671 39679 39732 39793 39831 39853 39890 39907 39916 39922 39970 40068 41445 41464 41610 41615 41630-41631 41651 41663 41689 41757 42080 42213-42214 42220-42221 42236 42279 42283 42296 42324 42366 42383 42394 42405 42408 42410 42428 42449 42470 42483 42932 42948 42977 42980-42981 42994 43014 43024 43030 43033 43062 43086 43099 43531 44028 44305 44312 44360 44366 44378 44389 44469 44717 44738 44822 44974 45594 45964 47033 47121 47593 47648 47909 48199 48474 48497 48534 48584 48663 48829 48965https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/404/1321?format=asciiOpticaldefaultJ/MNRAS/404/1321/tablea1Component structures for Galactic sight lines for which high-resolution (FWHM<2km/s) CaII spectra are availablerecnoRecord number assigned by the VizieR team.
