Iterative transit search using K2SFF data with BLS (left) and TLS (right). Planets K2-32 b, d, and c are successively detected with strong signals (see labels) with both BLS and TLS. Using a common detection threshold value of 9, however, planet e is not detected with BLS (SDE_BLS = 8.9), but it is detected with TLS (SDE_TLS = 13.2). The major peak near P = 0.4 d with (SDE_BLS = 10.5) in the fourth iteration of BLS is a false positive (blue marker). It overshadows the true transit signal near P = 4.3 d with (SDE_BLS = 8.9).
