Kepler planetary candidates. V. 3yr Q1-Q12

We provide updates to the Kepler planet candidate sample based upon 3yr (Q1-Q12) of data. Through a series of tests to exclude false-positives, primarily caused by eclipsing binary stars and instrumental systematics, 855 additional planetary candidates have been discovered, bringing the total number known to 3697.

We provide revised transit parameters and accompanying posterior distributions based on a Markov Chain Monte Carlo algorithm for the cumulative catalog of Kepler Objects of Interest. There are now 130 candidates in the cumulative catalog that receive less than twice the flux the Earth receives and more than 1100 have a radius less than 1.5R_{Earth}_. There are now a dozen candidates meeting both criteria, roughly doubling the number of candidate Earth analogs.
