cds-question@unistra.frmolecular-cloudsinterstellar-mediumco-line-emissionWe mapped 21 star-forming regions with the ^12^CO, ^13^CO and C^18^O (1-0) lines using the 13.7-m telescope of Purple Mount Observatory. This mapping survey resolved 53 ^13^CO cores, of which 22 are sourceless. We obtained the physical parameters of these cores. The relation between ^13^CO linewidth and core size and that between column density and core size were analysed. The cores 00211+6549-1 and 22566+5830 were found to have outflows. Systematic VLSR shifts were detected in nine regions: 00211+6549, 00232+6437, 05168+3634, 19199+1358, 20160+3911, 22566+5830, 23042+6000, S146 and S270. Signatures of infall and cloud collision were found in regions 18507+0121 and 19199+1358, respectively. We studied the mass function of these ^13^CO cores. The core masses range from 3.40 to 4.64x10^4^M_{sun}_, and the core mass function is a power-law distribution of index -0.82+/-0.04.2008MNRAS.391..869Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/391/869CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/391/869https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/391/869http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/391/869https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/391/869https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/391/869http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/391/869GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/391/869/table1 (Observed parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/391/869/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/391/869/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/391/869/table1?GETtext/xml+votable180.050000true5.97916766.1013890.005555555555555556Cone search capability for table J/MNRAS/391/869/table2 (Excluded regions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/391/869/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/391/869/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/391/869/table2?GETtext/xml+votable180.050000true353.08557.85955560.0055555555555555566/1307 1344 1606 2973 3039 3188 3649 3730 3746-3747 3848-3849 12686 12957 13050 14202 14293 14304 14306-14307 14309 14311 14314 14403 14622 14646 14652 15452 15627 21438-21439 22122 22243 22866 23760 23767 23938 23982-23983 24353 24426 29535 30318 30416-30417 30422 30595 30694 31832https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/391/869?format=asciiRadiodefaultJ/MNRAS/391/869/table1Observed parametersrecnoRecord number assigned by the VizieR team.
