cds-question@unistra.frmolecular-cloudsinfrared-sourcesmillimeter-astronomysubmillimeter-astronomyWe present an investigation of candidate infrared dark cloud (IRDC) cores as identified by Simon et al. (2006, Cat. J/ApJ/639/227) located within the Submillimetre Common User Bolometer Array (SCUBA) Legacy Catalogue. After applying a uniform noise cut to the catalogue data, we identify 154 IRDC cores that were detected at 850um and 51 cores that were not. We derive column densities for each core from their 8um extinction and find that the IRDCs detected at 850um have higher column densities (a mean of 1.7x10^22^cm^-2^) compared to those cores not detected at 850um (a mean of 1.0x10^22^cm-2).2009MNRAS.399.1506Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/399/1506CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/639/227 : MSX IRDC candidate catalog (Simon+, 2006)J/ApJ/641/389 : Millimetric observations of IRDC cores (Rathborne+, 2006)J/ApJ/680/349 : Galactic distribution of IRDCs (Jackson+, 2008)J/ApJ/686/384 : ^12^CO, ^13^CO, C^18^O survey of IRDCs (Du+, 2008)J/ApJS/175/277 : Submillimeter-Continuum SCUBA detections (Di Francesco+, 2008)J/ApJ/698/324 : Spitzer IRDCs (Ragan+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/399/1506https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/399/1506http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/399/1506https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/399/1506https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/399/1506http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/399/1506GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/399/1506/table1 (Data for all MSX identified IRDC candidate cores within the SCUBA Legacy Catalogue, with a SCUBA detection)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/399/1506/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/399/1506/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/399/1506/table1?GETtext/xml+votable180.050000true266.230833-28.7772220.005555555555555556Cone search capability for table J/MNRAS/399/1506/table2 (Data for all MSX identified IRDC candidate cores within the SCUBA Legacy Catalogue, with no detection at 850um)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/399/1506/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/399/1506/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/399/1506/table2?GETtext/xml+votable180.050000true266.661667-28.8822220.005555555555555556Cone search capability for table J/MNRAS/399/1506/table3 (Mass estimates for clouds with distances obtained by the GRS survey (Jackson et al., 2008, Cat.
