Shape quality piecewise χ² veto, illustrated for Kepler target KIC008590354. The blue points represent the whitened flux around a trigger that was identified by the template shown in the black line. Orange lines show the template split into segments, with independent amplitude fits for each. Orange shading represents the 1σ confidence interval for these fits. The three panels show the splitting of the template into two, three, and four parts. In this case, the test identified inconsistency in the segment amplitudes, indicating that the template does not adequately describe the data.
