Through submm dust continuum mapping, we attempt to search for genuine infrared-dark clouds (IRDCs) and precursors to massive stars and stellar clusters in the Galactic plane, and to determine their basic physical properties. We have mapped four selected fields of about 0.5degx0.5deg that contain Spitzer 8-um dark regions with LABOCA at 870um. Selected positions in the fields were observed in C^17^O(2-1) to obtain kinematic information. The obtained LABOCA maps are used in conjunction with the Spitzer IR images.2012A&A...542A.101Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/542/A101CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/680/349 : Galactic distribution of IRDCs (Jackson+, 2008)J/ApJ/639/227 : MSX IRDC candidate catalog (Simon+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/542/A101https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/542/A101http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/542/A101https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/542/A101https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/542/A101http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/542/A101GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/542/A101/table3 (Characteristics of the clumps identified from the LABOCA maps)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/542/A101/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/542/A101/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/542/A101/table3?GETtext/xml+votable180.050000true267.433333-27.5577780.0055555555555555566/28831 28874 29099 29112 291142.283270615984385e-22 2.283270615984385e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/542/A101?format=asciiOpticalRadiodefaultJ/A+A/542/A101/notesNotesrecnoRecord number assigned by the VizieR team.
