cds-question@unistra.fropen-star-clustersinfrared-photometryWe describe IRAC 3.6-8um observations and ground-based near-IR JHKs photometry from Mimir and 2MASS of the massive double cluster h and chi Persei complete to J=15.5 (M~1.3M_{sun}_). Within 25' of the cluster centers we detect ~11000 sources with J<=15.5, ~7000 sources with [4.5]<=15, and ~5000 sources with [8]<=14.5. In both clusters the surface density profiles derived from the 2MASS data decline with distance from the cluster centers as expected for a bound cluster. Within 15' of the cluster centers, ~50% of the stars lie on a reddened ~13Myr isochrone; at 15'-25' from the cluster centers, ~40% lie on this isochrone. Thus, the optical/2MASS color-magnitude diagrams indicate that h and chi Per are accompanied by a halo population with roughly the same age and distance as the two dense clusters.2007ApJ...659..599Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/659/599CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/27 : Proper Motions and UBV Photometry in h+chi Per (Muminov 1980)J/AJ/122/248 : h and chi Per UBVI,H{alpha} photometry (Keller+, 2001)J/A+A/394/479 : uvby{beta} photometry of h and chi Per (Capilla+, 2002)J/ApJ/576/880 : CCD UBV photometry of h and {chi} Per (Slesnick+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/659/599https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/659/599http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/659/599https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/659/599https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/659/599http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/659/599GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/659/599/table2 (h & chi Persei data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/659/599/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/659/599/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/659/599/table2?GETtext/xml+votable180.050000true34.928156.93910.0055555555555555565/814 6/3245 3247 3250 3251 3260https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/659/599?format=asciiInfrareddefaultJ/ApJ/659/599/table2h & chi Persei datarecnoRecord number assigned by the VizieR team.
