discov_num notes refcode
KOI2421 The system hosts a 0.7 Rearth planet candidate with a 2.3 day orbit
(Batalha et al. 2013). We detected two companions 0.42 and 2.62 Ks KOI2013a
mags fainter than KOI 2421 at separations of 1".12 and 4".0,
respectively. The closer companion is predicted to be Kp = 15.1 (dKp =
0.7), the farther companion Kp = 17.8 (dKp = 3.5). Due to the similar
brightness of the innermost companion and KOI2421, this system will
require a significant dilution correction. If all light from the
innermost companion is captured in the Kepler aperture and the planet
orbits the target star, the planet radius measurement will need to be
increased by 23% to account for dilution. KOI2421 does not exhibit a
large source offset during transit, which lends support to the theory
that the planet candidate orbits the target star, but the system
should be inspected closely to confirm this. Dre2014
