cds-question@unistra.frh-ii-regionsinfrared-photometryL-band data of RCW 57 at 3.5 micron taken with SPIREX (South Pole Infrared Explorer) is presented. The photometry was combined with 2MASS JHK data at 1.25 -2.2 micron. Colour-colour and colour-magnitude diagrams are constructed and used to determine the sources with infrared excess. These are interpreted as circumstellar disks, and enable the fraction of sources with disks (the cluster disk fraction or CDF) to be determined. We find that more than 50% of the sources detected at L-band in RCW 57 have an IR-excess.2006A&A...450..253Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/450/253CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/438/663 : JHKL photometry of 30 Dor (Maercker+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/450/253https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/450/253http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/450/253https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/450/253https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/450/253http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/450/253GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/450/253/table5 (Magnitudes for all sources (including foreground sources and sources below the 90% completeness limit) in RCW 57)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/450/253/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/450/253/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/450/253/table5?GETtext/xml+votable180.050000true167.708333-61.3056110.0055555555555555566/379238.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/450/253?format=asciiInfrareddefaultJ/A+A/450/253/table5Magnitudes for all sources (including foreground sources and sources below the 90% completeness limit) in RCW 57recnoRecord number assigned by the VizieR team.
