cds-question@unistra.frinterstellar-mediumline-intensitiesDiffuse interstellar bands (DIBs) can trace different conditions of the interstellar medium (ISM) along the sightline toward the observed stars. A small survey was made in optical wavelengths, producing high-resolution and high signal-to-noise spectra. We present measurements of 19 DIBs' properties in 50 sightlines toward hot stars, distributed at a variety of galactic coordinates and interstellar reddening. Equivalent widths were obtained by fitting asymmetric Gaussian and variable continua to DIBs. Conditions of the ISM were calculated from eight atomic and molecular interstellar lines. Two distinctly different types of DIBs were identified by carefully comparing correlation coefficients between DIBs and reddening and by different behavior in UV-shielded ({zeta}) and nonshielded ({sigma}) sightlines. A ratio of DIBs at 5780{AA} and 5797{AA} proved to be reliable enough to distinguish between two different sightline types. Based on the linear relations between DIB equivalent width and reddening for {sigma} and {zeta} sightlines, we divide DIBs into type I (where both linear relations are similar) and type II (where they are significantly different). The linear relation for {zeta} type sightlines always shows a higher slope and larger x-intercept parameter than the relation for {sigma} sightlines. Scatter around the linear relation is reduced after the separation, but it does not vanish completely. This means that UV shielding is the dominant factor of the DIB equivalent width versus reddening relation shape for {zeta} sightlines, but in {sigma} sightlines other physical parameters play a major role. No similar dependency on gas density, electron density, or turbulence was observed. A catalog of all observed interstellar lines is made public.2013ApJ...774...72Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/774/72CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/774/72https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/774/72http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/774/72https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/774/72https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/774/72http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/774/72GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/774/72/lines (Parameters of interstellar lines)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/774/72/lines?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/774/72/lines?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/774/72/lines?GETtext/xml+votable180.050000true273.978939-13.5743760.0055555555555555566/1198 1209 1212 1302 1539 1550 1554 1748 2884 3011 3188 3260 3308 3384 8490 14305 14630 14646 14654 14690 14691 15568 15573 15631 15652 15659 15672 15683 15686 15689 15692 15732 15747 15748 19202 22862 23646 23717 23999 24241 24303 29463 29621 29838 30630https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/774/72?format=asciiOpticaldefaultJ/ApJ/774/72/linesParameters of interstellar linesHDHD number of the starmeta.id;meta.mainintEW(4428)?
