Database Column Name 
Table Label  Description 

kepid†  KOI Host Star KIC ID 
The Kepler Input Catalog number of the target star hosting this KOI. 
kepoi_name†  KOI Name  The Kepler Object of Interest Name. 
pp_koi_period  KOI Transit Period [days]  The orbital period for this KOI used in the relative probability computation. 
pp_koi_time0bk  KOI Transit Epoch [BKJD=BJD2454833]  The orbital epoch in BKJD for this KOI used in the probability computation. 
pp_koi_depth  KOI Transit Depth [ppm]  The observed KOI transit depth in parts per million used in the probability computation. 
Database Column Name 
Table Label  Description 

pp_host_rel_prob†  Host Star Relative Probability  The relative probability that the KOI is due to a transit event at the same location as the host star. 
pp_host_prior_prob  Host Star a Priori Background Probability  The a priori probability that the transit is due to the KOI host star, to be used in a statistical sense when the relative probability computation has failed and no position information is available. See Section 5.2 of Planet Reliability Metrics: Astrophysical Positional Probabilities (KSCI19092). 
pp_host_prob_prov  KOI Host Star Relative Probability Source Flag  A text string indicating indicating the source of the KOI host star relative probability value. Current values flags include:

pp_host_prob_score†  Host Star Probability Usability Score  A value from 0 to 1 indicating whether the probability computation is trustworthy, with 1 indicating completely trustworthy. A value below 0.3 indicates that the relative probability computation is likely untrustworthy. See Section 5.1 of Planet Reliability Metrics: Astrophysical Positional Probabilities (KSCI19092). 
Database Column Name 
Table Label  Description 

pp_1hi_starid†  HighestProbability Star ID  The identifier of the star with the highest relative probability of being in the same location as the transit signal. 
pp_1hi_ra  HighestProbability Star RA [decimal degrees]  Right ascension in degrees of the star with the highest relative probability. 
pp_1hi_dec  HighestProbability Star Dec [decimal degrees]  Declination in degrees of the star with the highest relative probability. 
pp_1hi_kepmag  HighestProbability Star Keplerband Magnitude  Kepler magnitude of the star with the highest relative probability. 
pp_1hi_rel_prob†  HighestProbability Star Relative Probability  The relative probability that the KOI is due to a transit event at the same location as this star. 
pp_1hi_mod_depth  HighestProbability Star Modeled Transit Depth [ppm]  The modeled transit depth assuming that the KOI is due to a transit on this star. This value is strongly sensitive to catalog error, so stars with modeled depths up to 3 million parts per million are considered in the relative probability computation. 
pp_1hi_prob_prov  HighestProbability Star Provenance Flag  The source of the position and magnitude data for this star.

pp_2hi_starid†  SecondHighest Probability Star ID  The identifier of the star with the second highest relative probability of being in the same location as the transit signal. 
pp_2hi_ra  SecondHighest Probability Star RA [decimal degrees]  Right ascension in degrees of the star with the second highest relative probability. 
pp_2hi_dec  SecondHighest Probability Star Dec [decimal degrees]  Declination in degrees of the star with the second highest relative probability. 
pp_2hi_kepmag  SecondHighest Probability Star KeplerBand Magnitude  Kepler magnitude of the star with the second highest relative probability. 
pp_2hi_rel_prob†  SecondHighest Probability Star Relative Probability  The relative probability that the KOI is due to a transit event at the same location as this star. 
pp_2hi_mod_depth  Secondhighest Probability Star Modeled Transit Depth  The modeled transit depth assuming that the KOI is due to a transit on this star. This value is strongly sensitive to catalog error, so stars with modeled depths up to 3 million parts per million are considered in the relative probability computation. 
pp_2hi_prob_prov  Second highest probability star provenance flag  The source of the position and magnitude data for this star.
