cds-question@unistra.frspectroscopyline-intensitiesWe analyse abundances and rotational temperatures of the interstellar CN molecule. We have calculated the column densities and excitation temperatures of the molecule along 73 lines of sight basing on our original measurements of the B^2^{SIGMA}^+^-X^2^{SIGMA}^+^(0,0) vibrational band recorded in high signal-to-noise ratio spectra and also for 88 directions based on measurements already available in literature. We compare the column densities obtained from different bands of CN molecule available to ground-based instruments. The obtained excitation temperatures in the analysed directions show always an excess over the cosmic microwave background radiation (CMBR) temperature.2008MNRAS.390.1733Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/390/1733CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/390/1733https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/390/1733http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/390/1733https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/390/1733https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/390/1733http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/390/1733GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/390/1733/table1 (The list of observed stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/390/1733/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/390/1733/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/390/1733/table1?GETtext/xml+votable180.050000true52.267223159.940330.0055555555555555566/375 859 1048 1055 1060 1134 1196 1198 1293 1539 3284 3604 14251 14655 15476 15478-15479 15486 15580 15624-15625 15631 15656-15657 15659-15660 15662-15663 15672 15682-15683 15745 15747-15748 19009 21646 22223 22249 23851 24504 28915 29085 29097 29116 29162 29463 29504 29522 29537 29621 29876 30722 30818 37153 37316 37754 37841 37851 37863 37874 37880 37897 37900 37923 37926 37948 38016 39248 39252 39281 39334 39733 39752-39754 39780 41631 41651 41654 41657 41662-41663 41757 42149 42213-42214 42221 42383 42394 42405 42408 42470 42477 42980-42982 42988 42994 43024 43026 43086 47828https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/390/1733?format=asciiOpticaldefaultJ/MNRAS/390/1733/table1The list of observed starsrecnoRecord number assigned by the VizieR team.
