The procedure was applied to the CO J=3-2 line data, obtained using the James Clerk Maxwell Telescope, to identify 184 high-velocity dispersion compact clouds (HVDCCs), which are a category of peculiar molecular clouds found in the central molecular zone of our Galaxy. A list of HVDCCs in the area -1.4{deg}<=l<=+2.0{deg}, -0.25{deg}<=b<=+0.25{deg} was presented with their physical parameters, CO J=3-2/J=1-0 intensity ratios, and morphological classifications. Consequently, the list provides several intriguing sources that may have been driven by encounters with pointlike massive objects, local energetic events, or cloud-to-cloud collisions.2022ApJS..261...13Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/261/13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/391/159 : A search for Compact High-Velocity Clouds (De Heij+, 2002)J/AJ/123/873 : HIPASS high-velocity clouds (Putman+, 2002)J/ApJ/623/181 : Compact high-velocity cloud photometry catalog (Siegel+, 2005)J/ApJ/768/77 : Ultra-compact high velocity clouds from ALFALFA (Adams+, 2013)J/ApJ/806/95 : A search for ultra-compact HVC counterparts (Sand+, 2015)J/ApJS/234/22 : SCUBA-2 Galactic Center compact source catalog (Parsons+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/261/13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/261/13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/261/13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/261/13https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/261/13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/261/13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/261/13/hvdcc (Catalog of high-velocity dispersion compact clouds (HVDCCs) and physical parameters (Tables 4 and 5))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/261/13/hvdcc?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/261/13/hvdcc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/261/13/hvdcc?GETtext/xml+votable180.050000true265.64166-30.172550.0055555555555555565/7206 6/28830-28831 28874https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/261/13?format=asciiRadiodefaultJ/ApJS/261/13/hvdccCatalog of high-velocity dispersion compact clouds (HVDCCs) and physical parameters (Tables 4 and 5)recnoRecord number assigned by the VizieR team.
