Notes.

^(*)

Orbital period, Kepler magnitude (K_p), transit depth and expected planetary radius from Borucki et al. (2011b) and Ba12. The expected planetary radius may have uncertainty up to 30% (Borucki et al. 2011b).

^(**)

Vetting flag from Borucki et al. (2011b): “1” for “confirmed and published planet”; “2” for “Strong probability candidate, cleanly passes tests that were applied”; “3” for “moderate probability candidate, not all tests cleanly passed but no definite test failures”.

^(⋆)

False Positive Probability as estimated by Morton & Johnson (2011).

^(†)

No var: no significant RV variation; blend: triple system or background eclipsing binary; SB1: single-line spectroscopic binary; no FUp: no follow-up observation with SOPHIE; BD: Brown dwarf with mass in between 25 M_Jup and 80 M_Jup.
