The observed J=6-5/J=1-0 ^12^CO integrated temperature ratios range from 0.10 to 0.45 in matching beams. Multi-aperture data indicate that the emission of ^13^CO(6-5) is more centrally concentrated than that of ^12^CO(6-5). The intensities of ^12^CO(6-5) suggest a correlation with those of HCO+ but not with those of HCN. The new data are essential in refining and constraining the parameters of the observed galaxy center molecular gas in a simple two-phase model to approximate its complex multi-phase structure. In all galaxies except the Seyfert galaxy NGC 1068, high-J emission from the center is dominated by a dense (n~10^5^cm^-3^) and relatively cool (20-60K) high-pressure gas. In contrast, the low-J lines are dominated by low-pressure gas of a moderate density (n~10^3^cm^-3^) and more elevated temperature (60-150K) in most galaxies. The three exceptions with significant high-pressure gas contributions to the low-J emission are all associated with active central star formation.2024A&A...691A.289Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/691/A289CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/691/A289https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/691/A289http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/691/A289https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/691/A289https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/691/A289http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/691/A289GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/691/A289/table2 (galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/691/A289/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/691/A289/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/691/A289/table2?GETtext/xml+votable180.050000true11.887917-25.2883330.005555555555555556Cone search capability for table J/A+A/691/A289/list (List of fits ^12^CO(6-5) and ^13^CO(6-5) spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/691/A289/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/691/A289/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/691/A289/list?GETtext/xml+votable180.050000true40.6698-0.013430.0055555555555555566/3506 7606 16655 17754 18387 31158 34273 34531 35691 35993 40454 43233 43881https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/691/A289?format=asciiRadiodefaultJ/A+A/691/A289/table2galaxiesrecnoRecord number assigned by the VizieR team.
