WDS 19187+4042 KOI 1677 AB : NOTES

discov_num	notes	refcode
KOI1677	KOI1677 hosts a 2.2 Rearth planet candidate with a 52.1 day orbit and
	a 0.8 Rearth candidate with a 8.5 day orbit (Batalha et al. 2013).	KOI2013a
	Assuming that all of the flux from the target star and the companion
	is captured in the Kepler aperture and that the planet orbits the
	target star, the planet radius estimate should be increased by roughly
	2% to account for the contamination from the nearby star.	Dre2014
