The condition flag is a single, semi-colon separated string of phrases, in alphabetical order, describing various target categories and conditions known about a particular Kepler target or system (in some cases multiple flags indicate a multi-KOI system with different dispositions). The table below provides information on each of the currently flagged conditions. Note the table below lists the total number of flagged "stellar targets", not the number of "KOIs" or "observations".
You can also use the "user-specified field" form element to try more advanced condition flag searches. Note that if you use the user-specified field be sure the Condition Flag box entry is set to "All Targets", otherwise any other selected value will be included in the search.
| Condition Flag | # of Flagged Host Stars | Description |
|---|---|---|
| Eclipsing_binary | 2,399 | Targets listed in the unpublished beta version of the Kepler eclipsing binary catalog revision 3.0, as last updated on 17 June, 2013. See the Eclipsing Binaries table for more information. |
| False_positive | 2136 | Targets showing planetary transit-like features but which further analysis concluded was not attributable to a planet. As of January, 2013, the false positives are flagged using the "FALSE POSITIVE" disposition flag from the Kepler Objects of Interest (KOI) table. |
| Planetary_candidate | 2,647 | A target exhibiting photometric features consistent with a transiting planet (but not necessarily confirmed). As of January, 2013, the planetary candidates are flagged using the "CANDIDATE" disposition flag from the Kepler Objects of Interest (KOI) table. Not that confirmed exoplanets are NOT included in the "Planetary_candidate" category. |
| Exoplanet | 83 | A host star confirmed (i.e., published) to have 1 or more orbiting exoplanets. As of January, 2013, this flag is based on NExScI's compiled list of ipublished Exoplanets. Note most, but not all, targets flagged as confirmed planets are KOIs. |
| Not Dispositioned | 25 | A Kepler Object of Interest (KOI) which requires further analysis before being assigned a disposition. In other words, it has not yet been determined if the object is a False Positive, or a planetary candidate. It is expected that "not displositioned" KOIs will eventually be assigned a disposition. Note that KOIs refer to individual components of possibly multi-component systems, some components of which have already been identified. This explains condition-flags such as "Exoplanet; Not Dispositioned". |
| Red_giant | 15,626 | A possible red giant star. See the Red Giant Release page for more information. |
| Possible_artifact | 36,000 | A target believed to be flagged by the Kepler project as a possible artifact. These targets were identified by having row and column positions indicating they are on the detector, but the project did not provide distance to edge values. The distance values shown were added by MAST. They differ from the project-defined distances in that they represent the minimum distance from the detector edge to the target not (more accurately) from the detector edge to the edge of the photometric aperture. Note no targets considered "off" the detector were flagged as possible artifacts. |
| Null_kepmag | 120,000 | A KIC target without a value for the Kepler magnitude. These were originally included in the target search interface, were later removed (July, 2011) by the Kepler project, then re-added by MAST with MAST-defined distance to edge values. As for the "possible_artifact" case, the MAST-defined distances describe the distance from the detector edge to the target, not from the detector edge to the edge of the photometric aperture. Most galaxies are included in this group. |
