Datasets 3a–3d consider two anomalies that overlap during a few days. Two block functions should be identified. The start and end columns of the block function describing the first anomaly should be 5 and 15, and the amplitude should be 10 m3/h. For the second anomaly the start and end columns of the block function should be 12 and 20, and the amplitude should be 5 m3/h. Table 5 summarizes the results obtained by performing the different tests.
