cds-question@unistra.frsurveysvariable-starsquasarsIn area and depth, the Pan-STARRS1 (PS1) 3{pi} survey is unique among many-epoch, multi-band surveys and has enormous potential for the all-sky identification of variable sources. PS1 has observed the sky typically seven times in each of its five bands (grizy) over 3.5 years, but unlike SDSS, not simultaneously across the bands. We developed a new approach for quantifying statistical properties of non-simultaneous, sparse, multi-color light curves through light curve structure functions, effectively turning PS1 into a {sim}35-epoch survey. We use this approach to estimate variability amplitudes and timescales for point sources brighter than r_P1_=21.5 mag in the survey. On this basis we provide a catalog of all likely variable point sources and likely QSOs in PS1.2016ApJ...817...73Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/817/73CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/817/73https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/817/73http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/817/73https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/817/73https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/817/73http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/817/73GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJ/817/73/listList of available catalogsrecnoRecord number assigned by the VizieR team.
