Eccentricity posteriors for planets in single-star systems (left column) and binaries (right column). Dashed lines mark the 68.2th percentile of points around the statistical mode. For all of the single-star systems this includes the lowest e bin, so a single line (68.2% upper limits) is indicated instead. Colors are applied to the histograms in multi-planet systems to distinguish the distributions; for Kepler-1319 (KOI-2705) the black distribution is if the planet orbits the primary, while the red is assuming it orbits the companion.
