Kepler Candidates

A graph/scatter plot of radius vs period for Kepler planet candidates. Comparing the distributions from 2010-2011 (blue), 2012 (red), and 2013 (yellow), notice how more and more small planets are revealed. This plot excludes “single-transit” events. Period for single transit events must be estimated from the transit duration. Here we demand 2 or more transits for the plot.
