cds-question@unistra.frsurveysmultiple-starssolar-system-planetsThe Kepler Mission is searching for Earth-size planets orbiting solar-like stars by simultaneously observing >160000 stars to detect sequences of transit events in the photometric light curves. The Combined Differential Photometric Precision (CDPP) is the metric that defines the ease with which these weak terrestrial transit signatures can be detected. An understanding of CDPP is invaluable for evaluating the completeness of the Kepler survey and inferring the underlying planet population. This paper describes how the Kepler CDPP is calculated, and introduces tables of rms CDPP on a per-target basis for 3-, 6-, and 12-hr transit durations, which are now available for all Kepler observations. Quarter 3 is the first typical set of observations at the nominal length and completeness for a quarter, from 2009 September 18 to 2009 December 16, and we examine the properties of the rms CDPP distribution for this data set. Finally, we describe how to employ CDPP to calculate target completeness, an important use case.2012PASP..124.1279Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/124/1279CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)http://archive.stsci.edu/kepler/ : Kepler archives Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/124/1279https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/124/1279http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/124/1279https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/124/1279https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/124/1279http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/124/1279GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/124/1279/table1 (Q3 table of rms Combined Differential Photometric Precision (CDPP))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/124/1279/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/124/1279/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/124/1279/table1?GETtext/xml+votable180.050000true291.0387336.59812890.0055555555555555564/922-923 933-935 944-946 5/3645-3647 3683 3704 3706 3729-3731 3760 3765 3788-3789 3792-3793 6/14559 14567 14573 14575 14577-14579 14730-14731 14738 14744 14746-14747 14749-14751 14792 14794-14795 14822 14828 14830-14831 14914-14915 15044-15045 15056-15057 15059 15160-15161 15164 15176-15178 15200 15202 15232-15233https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/124/1279?format=asciidefaultJ/PASP/124/1279/table1Q3 table of rms Combined Differential Photometric Precision (CDPP)recnoRecord number assigned by the VizieR team.
