cds-question@unistra.frgalaxiesmolecular-cloudsWe present an analysis of a systematic CO(2-1) survey at 12" resolution covering most of the Local Group spiral M33, which, at a distance of 840kpc, is close enough for individual giant molecular clouds (GMCs) to be identified. The goal of this work is to study the properties of the GMCs in this subsolar metallicity galaxy. The CPROPS (Cloud PROPertieS) algorithm was used to identify 337 GMCs in M33, the largest sample to date for an external galaxy. The sample is used to study the GMC luminosity function, or mass spectrum under the assumption of a constant N(H_2_)/I_CO_ ratio.2012A&A...542A.108Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/542/A108CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/522/A3 : M33 CO(2-1) and HI integrated intensity maps (Gratier+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/542/A108https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/542/A108http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/542/A108https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/542/A108https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/542/A108http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/542/A108GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/542/A108/tablea1 (Clouds detected in CO)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/542/A108/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/542/A108/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/542/A108/tablea1?GETtext/xml+votable180.050000true23.300139230.38373280.0055555555555555566/2154-2155https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/542/A108?format=asciiOpticaldefaultJ/A+A/542/A108/tablea1Clouds detected in COrecnoRecord number assigned by the VizieR team.
