cds-question@unistra.fropen-star-clustersproper-motionsFrom photographic plate data of Shanghai Astronomical Observatory with a time baseline of 87 years, proper motions and membership probabilities of 364 stars in the open cluster NGC 6530 region are reduced. On the basis of membership determination, luminosity function and segregation effect of the cluster are discussed with details. Spatial mass segregation is obviously present in NGC 6530 while there is no clear evidence for a velocity-mass (or velocity-luminosity) dependence. The observed spatial mass segregation for NGC 6530 might be due to a combination of initial conditions and relaxation process.2006ChJAA...6..435Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ChJAA/6.435CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/123/63 : NGC 6530 multi-wavelength photometry (van den Ancker+ 1997)J/AJ/120/333 : UBVRI and H{alpha} in NGC 6530 (Sung+, 2000)J/A+A/395/499 : XMM observations in M8 and NGC6530 (Rauw+, 2002)J/ApJ/608/781 : NGC 6530 Chandra X-ray catalog (Damiani+, 2004)J/A+A/430/941 : Star formation region NGC 6530 (Prisinzano+, 2005)J/A+A/462/123 : VLT/Flames spectroscopic data of NGC 6530 (Prisinzano+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/ChJAA/6.435https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/ChJAA/6.435http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/ChJAA/6.435https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/ChJAA/6.435https://vizier.iucaa.in/viz-bin/votable?-source=J/other/ChJAA/6.435http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/ChJAA/6.435GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/ChJAA/6.435/table5 (Proper motions and membership probabilities of 364 stars in the region of NGC 6530)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/ChJAA/6.435/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/other/ChJAA/6.435/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/ChJAA/6.435/table5?GETtext/xml+votable180.050000true270.5189-24.634819440.0055555555555555565/7222 6/28912 28913https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/ChJAA/6.435?format=asciiOpticaldefaultJ/other/ChJAA/6.435/table5Proper motions and membership probabilities of 364 stars in the region of NGC 6530recnoRecord number assigned by the VizieR team.
