Completeness as a function of purity for different thresholds of Einstein radii (expressed in terms of critical curve here) and signal-to-noise ratio with the two methods described in Sect. 3: polar transform (in red) and island finding (in blue). The minimal radius in the sample is r = 0.02′′, which means that the top left panel shows the results over the whole sample.
