cds-question@unistra.frinterstellar-mediumultraviolet-astronomyspectroscopyearly-type-starsWe present an analysis of interstellar NaI ({lambda}_air_=3302.37 and 3302.98{AA}), TiII ({lambda}_air_=3383.76{AA}) and CaIIK ({lambda}_air_=3933.66{AA}) absorption features for 74 sightlines towards O- and B-type stars in the Galactic disc. The data were obtained from the Ultraviolet and Visual Echelle Spectrograph Paranal Observatory Project (UVES POP), at a spectral resolution of 3.75km/s and with mean signal-to-noise ratios per pixel of 260, 300 and 430 for the NaI, TiII and CaII observations, respectively. Interstellar features were detected in all but one of the TiII sightlines and all of the CaII sightlines. The dependence of the column density of these three species with distance, height relative to the Galactic plane, HI column density, reddening and depletion relative to the solar abundance has been investigated. We also examine the accuracy of using the NaI column density as an indicator of that for HI. In general, we find similar strong correlations for both Ti and Ca, and weaker correlations for Na. Our results confirm the general belief that Ti and Ca occur in the same regions of the interstellar medium (ISM) and also that the TiII/CaII ratio is constant over all parameters. We hence conclude that the absorption properties of Ti and Ca are essentially constant under the general ISM conditions of the Galactic disc.2006MNRAS.367.1478Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/367/1478CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/367/1478https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/367/1478http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/367/1478https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/367/1478https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/367/1478http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/367/1478GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/367/1478/stars (The stellar sample: basic parameters and column densities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/367/1478/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/367/1478/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/367/1478/stars?GETtext/xml+votable180.050000true270.9685206-24.360730.0055555555555555566/20764 20975 21365 21515 22039 22258 22615 22850 22859 22911 23374 23581 23717 26867 28672 28687 28890 28915 28968 29085 29089 29162 29809 30722 32793 37245 37333 37364 37584 37777 37900 37926 37930 37948 38016 38073 39243 39252 39374 39679 39732 39793 39831 39890 39922 39970 41445 41464 41610 41615 41630-41631 41651 41757 41843 42214 42221 42283 42296 42394 42405 42410 42439 42483 42932 43008 43019 43030 43086 44360https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/367/1478?format=asciiUVOpticaldefaultJ/MNRAS/367/1478/starsThe stellar sample: basic parameters and column densitiesrecnoRecord number assigned by the VizieR team.
