WDS 19416+4259 KOI 266 : NOTES

discov_num	notes	refcode
KOI 266	This system contains a 1.6 Rearth planet candidate with a 25.3 day
	period and a second 1.8 Rearth planet candidate with a 47.7 day period
	(Burke et al. 2014). It was classified by Slawson et al. (2011) as a	KOI2014a
	detached eclipsing binary with a period of 25.3 days, suggesting that	KOI2011a
	the 1.6 Rearth planet candidate with the same period might not
	actually be a planet. Instead, the observed decrease in flux every
	25.3 days might be an eclipsing binary diluted by the light of a
	nearby star.	Dre2014
