Catalogue distribution in latitude (top), longitude (middle) and mass (bottom). The distribution of the input simulated catalogue is plotted as a solid line. The statistics of the output detection catalogue is given for the 3 best methods: CR 545/2997 (dot dot dot dash), WBS 545-2997 (dash) and WBS 545-857 (long dash). The red line in the bottom panel indicates the input power law of the mass distribution with an index α = 2.1.
