Completeness as a function of purity for the detection methods based on the S96 (blue), TANH (red), J04 (purple), and M18 (green) AM filters, the W4 wavelet filter (light blue), and the W234 wavelet filter (orange). The cross markers represent precisely where the methods are evaluated in terms of purity and completeness. The purity and the completeness are computed using a S/N > 2 halo pre-selection and averaging over the 256 realisations.
