Distributions of the impact parameter β estimates: panel a: over the whole list of KOIs in the NASA Exoplanet Archive. Panel b: for the KOIs from Table A.1 with β > 0.07 and r_se< 0. Panel c: for the KOIs from Table A.1 with β > 0.07 and r_se> 0. The ordinate value n is the number of β-estimates in a bin of histogram. Similarly to Fig. 3, color shows the status of objects within a bin: violet – probably non-planets (“n” in Table A.1); blue – candidates (“c” in Table A.1); green – confirmed planets, but with unknown masses (“p” in Table A.1); red – confirmed planets with measured planetary masses (“p!”in Table A.1). Cases with “*” and “?” are also included.
