Notes. Objects marked with an asterisk (*) in the companion column are assumed to be the Kepler object of interest. In the case of close companions with similar magnitudes, it is difficult to distinguish which is the actual host. The assumed KOI is the brightest object in the system. Companions marked with a “+” symbol indicate those probably bound according to Sect. 4.2.2. The last column shows the photometric error if we were to take into account the empirical errors in the software gain of the instrument.
