cds-question@unistra.frmolecular-cloudsmillimeter-astronomysubmillimeter-astronomyWe present an analysis of 3.5deg^2^ of submillimeter continuum and extinction data of the Perseus molecular cloud. We identify 58 clumps in the submillimeter map, and we identify 39 structures (cores) and 11 associations of structures (super cores) in the extinction map. The cumulative mass distributions of the submillimeter clumps and extinction cores have steep slopes (alpha~2 and 1.5-2, respectively), steeper than the Salpeter initial mass function (IMF; alpha=1.35), while the distribution of extinction super cores has a shallow slope (alpha~1). Most of the submillimeter clumps are well fit by stable Bonnor-Ebert spheres with 10K<T<19K and 5.5<log_10_(Pext/k)<0.6. The clumps are found only in the highest column density regions (AV>5-7mag), although Bonnor-Ebert models suggest that we should have been able to detect them at lower column densities if they exist.2006ApJ...646.1009Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/646/1009CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/638/293 : 1.1mm sources in the Perseus Molecular Cloud (Enoch+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/646/1009https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/646/1009http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/646/1009https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/646/1009https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/646/1009http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/646/1009GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/646/1009/table1 (Properties of Submillimeter Clumps in Perseus)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/646/1009/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/646/1009/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/646/1009/table1?GETtext/xml+votable180.050000true56.92333332.8633330.005555555555555556Cone search capability for table J/ApJ/646/1009/table2 (Properties of Extinction Cores in Perseus)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/646/1009/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/646/1009/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/646/1009/table2?GETtext/xml+votable180.050000true56.932532.8688890.005555555555555556Cone search capability for table J/ApJ/646/1009/table3 (Properties of Extinction Super Cores in Perseus)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/646/1009/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/646/1009/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/646/1009/table3?GETtext/xml+votable180.050000true56.9387532.8787220.0055555555555555566/855 857 858 859 860 861 862 881 884 1538 1539 1542 1544https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/646/1009?format=asciiRadiodefaultJ/ApJ/646/1009/table1Properties of Submillimeter Clumps in PerseusrecnoRecord number assigned by the VizieR team.
