Abstract:
We present the sixth catalog of Kepler candidate planets based on
nearly four years of high precision photometry. This catalog builds on
the legacy of previous catalogs released by the Kepler project and
includes 1493 new Kepler Objects of Interest (KOIs) of which 554 are
planet candidates, and 131 of these candidates have best-fit radii
<1.5R⊕. This brings the total number of KOIs and planet
candidates to 7348 and 4175 respectively. We suspect that many of
these new candidates at the low signal-to-noise ratio limit may be
false alarms created by instrumental noise, and discuss our efforts to
identify such objects. We re-evaluate all previously published KOIs
with orbital periods of > 50 days to provide a consistently vetted
sample that can be used to improve planet occurrence rate
calculations. We discuss the performance of our planet detection
algorithms, and the consistency of our vetting products.
Description:
The Q1-Q16 catalog is based on the analysis of 16 quarters of data
obtained by the Kepler spacecraft from 2009 May 13 to 2013 April 8.

Note (1): Status is;
FP = (false positive) we believe the KOI is not a bona-fide planet;
PC = (Planet Candidate) we have no compelling evidence that the signal
is not due to a planet.
Note (2): The v-shape statistic is not included at the Exoplanet Archive
and is described in Section 7: the metric is defined as V=1-b-Rp/R*,
where b is the impact parameter, and Rp/R* is the ratio of planet and
star radii. KOIs with V≲0 are more likely to be caused by eclipsing
binaries (EBs).
Note (3): Set for KOIs detected with three transits and MES<8 (MES =
Multiple Event Statistic). As discussed in Section 9.1, we expect
lower reliability for this population of candidates.
Note (4): In cases where the MCMC (Markov Chain Monte Carlo) fit failed to
converge we report the period and epoch of the detection only. Some
KOIs, such as K00423.02, have extremely large reported radii. These
are either extremely v-shaped transits that are difficult to fit with
a planet model, or low SNR false alarms where the MCMC fits struggle
to converge on a sensible value.
Note (5): In cases where only the lower uncertainty is given the e_Rad
value represents the 1σ uncertainty in the two least significant
digits.
