Revising the properties of the associated planet candidates based on the updated host star characteristics and refitting the transit photometry, we find that our sample contains 20 planets or planet candidates with radii smaller than 1.25 Earth radii, 20 super-Earths (1.25 - 2 Earth radii), 20 small Neptunes (2 - 4 Earth radii), three large Neptunes (4 - 6 Earth radii), and eight giant planets (> 6 Earth radii).

Comparing our sample to the Kepler candidate sample investigated by Fulton et al. (2017), we conclude that more planets are required to quantitatively confirm the gap with K2 candidates or validated planets.

Combining the new and previous KOI samples, we provide updated parameters for 2,738 Kepler planet candidates distributed across 2,017 host stars.

This study examines planet occurrence rates for the Kepler GK dwarf target sample for planet radii, 0.75... ▽ More We measure planet occurrence rates using the planet candidates discovered by the Q1 - Q16 Kepler pipeline search.

We show tentative evidence of a gap in the planet radius distribution of our candidate sample.

A comparison of stellar densities from asteroseismology with densities derived from transit models in Batalha et al. assuming circular orbits shows significant disagreement for more than half of the sample due to systematics in the modeled impact parameters, or due to planet candidates which may be in eccentric orbits.

Finally, we investigate tentative correlations between host - star masses and planet candidate radii, orbital periods, and multiplicity, but caution that these results may be influenced by the small sample size and detection biases.

Using the revised stellar properties, we recalculate the radii for 107 planet candidates in our sample, and comment on candidates for which the radii change from a previously giant - planet / brown - dwarf / stellar regime to a sub-Jupiter size, or vice versa.
