cds-question@unistra.frmillimeter-astronomysubmillimeter-astronomyinterstellar-mediumradio-astronomyNinety-six Planck cold dust clumps in the second quadrant were mapped with ^12^CO(1-0), ^13^CO(1-0), and C^18^O(1-0) lines at the 13.7m telescope of Purple Mountain Observatory. ^12^CO(1-0) and ^13^CO(1-0) emissions were detected for all 96 clumps, while C^18^O(1-0) emissions were detected in 81 of them. Fifteen clumps have more than one velocity component. In the 115 mapped velocity components, 225 cores were obtained. We found that 23.1% of the cores have non-Gaussian profiles. We acquired the V_lsr_, FWHM, and T_A_ of the lines. Distances, T_ex_, velocity dispersions, N_H_2__, and masses were also derived. Generally, turbulence may dominant the cores because {sigma}_NT_/{sigma}_Therm_>1 in almost all of the cores and Larson's relationship is not apparent in our massive cores. Virial parameters are adopted to test the gravitational stability of cores and 51% of the cores are likely collapsing. The core mass function of the cores in the range 0-1kpc suggests a low core-to-star conversional efficiency (0.62%). Only 14 of 225 cores (6.2%) have associated stellar objects at their centers, while the others are starless. The morphologies of clumps are mainly filamentary structures. Seven clumps may be located on an extension of the new spiral arm in the second quadrant while three are on the known outer arm.2016ApJS..224...43Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/224/43CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/224/43https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/224/43http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/224/43https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/224/43https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/224/43http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/224/43GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/224/43/table1 (Planck cold clumps in the second quadrant)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/224/43/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/224/43/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/224/43/table1?GETtext/xml+votable180.050000true331.250333351.55326110.005555555555555556Cone search capability for table J/ApJS/224/43/table2 (Observed parameters of the J=1-0 lines of ^12^CO, ^13^CO and C^18^O)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/224/43/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/224/43/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/224/43/table2?GETtext/xml+votable180.050000true331.239451.55690.005555555555555556Cone search capability for table J/ApJS/224/43/table3 (Parameters of the mapped cores)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/224/43/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/224/43/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/224/43/table3?GETtext/xml+votable180.050000true331.233369451.52020440.0055555555555555566/1330 1344 1346 1350 1352 1460 1470 1631 1788 1791 1812 1814 1825 1846 1847 1851 1852 1935 1937 1940 1959 1964 1968 3035 3156 3157 3185 3188 3255 3330 3331 3349 3353 3355 3356 3358 3365 3371 3375 3379 3458 3459 3625 3627 3628 3630 3634 3635 3645 3692 3716 3745 3747 3748 3777 3780 3813 3849 3850 3851 3873 14069 14199 14207 14306 15741 15746 15812 15816 15825 24474 24478 24487 24493 24501 24502 24508 24513 24515 24522 24526 24560 24562 24569https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/224/43?format=asciiMillimeterRadiodefaultJ/ApJS/224/43/table1Planck cold clumps in the second quadrantrecnoRecord number assigned by the VizieR team.
