FPP for each Kepler candidate (KOI) that we followed up with Spitzer as a function of the target star’s Galactic latitude and Kepler magnitude. The radii of the circles increase linearly as a function of the FPP value (largest circles for the largest FPP). The filled red circles in red colors correspond to the targets for which the FPP is lower than 0.3%, which could be considered as validated at the ﹩3\sigma ﹩ level of confidence. These validated planets represent one-fourth of the overall sample. The FPP clearly increases toward the bottom-right corner as expected.
