KOI2790	This system hosts a 0.9 Rearth planet candidate with a 14.0 day period
	(Burke et al. 2014). The approximate increase to the planet radius is	KOI2014a
	17% assuming that all of the light from the companion is captured in
	the Kepler aperture and that the planet orbits the target star.
	KOI2790 does not exhibit a significant source offset during transit.	Dre2014
