False association rate for different filter functions.
| Filter function | False association rate (%) | |
|---|---|---|
| S96 | 12.8 ± 0.3 | |
| TANH | 9.0 ± 0.3 | |
| J04 | 14.2 ± 0.4 | |
| M18 | 10.6 ± 0.4 | |
| W234 | 10.8 ± 0.4 | |
| W2 | 2.8 ± 0.3 | |
| W3 | 8.7 ± 0.4 | |
| W4 | 13.6 ± 0.4 |
Notes. The false association rate is computed for each detection method including each individual wavelet filter W2, W3 and W4. The fraction of false associations is estimated by matching random detection positions with the halo catalogues with a S/N > 2 halo pre-selection. The errors are computed using the 256 realisations.
