Notes. We show the number of detected companions for different separation ranges. The lower part of the table shows the statistics regardless whether the KOI still hosts planet candidates. We have 56 KOIs that have been demoted in the latest Kepler releases and are not classified as planet hosts any longer. In the case of Howell et al. (2011), there are 24 demoted KOIs, there are 16 for Adams et al. (2012, 2013), and there are 17 for Law et al. (2013). These results are presented int the third section of this table.
