cds-question@unistra.frradio-sourcesmagellanic-cloudsh-i-line-emission21cm neutral hydrogen interferometric survey of the Large Magellanic Cloud (LMC) combined with the Parkes multibeam HI single-dish survey (2003MNRAS.339...87S) clearly shows that the HI gas is distributed in the form of clumps or clouds. The HI clouds and clumps have been identified using a thresholding method with three separate brightness temperature thresholds (T_b_). Each catalog of HI cloud candidates shows a power-law relationship between the sizes and the velocity dispersions of the clouds roughly following the Larson law scaling {sigma}_v_{prop.to}R^0.5^, with steeper indices associated with dynamically hot regions. The clouds in each catalog have roughly constant virial parameters as a function of mass, suggesting that the clouds are all in roughly the same dynamical state, but the values of the virial parameter are significantly larger than unity, showing that turbulent motions dominate gravity in these clouds. The mass distribution of the clouds is a power law with differential indices between -1.6 and -2.0 for the three catalogs. In contrast, the distribution of mean surface densities is a lognormal distribution.2007ApJS..171..419Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/171/419CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/PASAu/6.471 : Magellanic Clouds bridge region HI profiles (McGee+ 1986)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/171/419https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/171/419http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/171/419https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/171/419https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/171/419http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/171/419GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/171/419/KRL2007 (Catalog of HI clouds)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/171/419/KRL2007?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/171/419/KRL2007?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/171/419/KRL2007?GETtext/xml+votable180.050000true67.665-69.090.0055555555555555564/2068 2070 5/8259 8261 8262 8263 8268 8269 8276 8277 8278 8284 6/33031 33035 33042 33043 33069 33080 33081 33083 33084 33085 33087 33116 33118 37514 37538https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/171/419?format=asciiRadiodefaultJ/ApJS/171/419/KRL2007Catalog of HI cloudsrecnoRecord number assigned by the VizieR team.
