Target Labels and Flags

Database Column Name Table Label Description
kepid† Kepler Identification or KepID Target identification number, as listed in the Kepler Input Catalog (KIC). The KIC was derived from a ground-based imaging survey of the Kepler field conducted prior to launch. The survey's purpose was to identify stars for the Kepler exoplanet survey by magnitude and color. The full catalog of 13 million sources can be searched at the MAST archive. The subset of 4 million targets found upon the Kepler CCDs can be searched via the Kepler Target Search form. The Kepler ID is unique to a target and there is only one Kepler ID per target.
kepoi_name† KOI Name A number used to identify and track a Kepler Object of Interest (KOI). A KOI is a target identified by the Kepler Project that displays at least one transit-like sequence within Kepler time-series photometry that appears to be of astrophysical origin and initially consistent with a planetary transit hypothesis. A KOI name has an integer and a decimal part of the format KNNNNN.DD. The integer part designates the target star; the two-digit decimal part identifies a unique transiting object associated with that star. It is not necessarily the planetary candidate listed in that order within a DV report, nor does it indicate the distance of the planet from the the host star relative to other planets in the system.
kepler_name† Kepler Name Kepler number name of the form "Kepler-N" plus a lower-case letter identifying the planet. In general, these numbers are easier to remember than the corresponding KOI or KIC/KepID designations and are intended to clearly indicate a class of objects that have been confirmed or validated as planets—a step up from the planet candidate designation.
alt_name† Confirmed Name The planet name as used in the Exoplanet Archive confirmed planet table.
koi_list_flag† Is In KOI List? This flag indicates whether the planet is listed in the KOI candidate list (value of "YES") or not (value of "NOT"). KOI candidates are identified through transit signatures from the Kepler light curves. Follow-up observations may confirm the presence of additional planets via signatures that are not those of transiting objects, for example via Transit Timing Variations.
tm_designation 2MASS Name 2MASS designation from the 2MASS point source catalog (Skrutskie et al. 2006, ApJ, 131, 1163).
last_update† Date of Last Update Date of last update for this Kepler planet
