After addition of the noise, FON can no longer detect the true anomaly signal in week 43, and detects the anomaly in week 44 with a graph distance that is very close to the 2σ threshold. Furthermore, FON shows false positives in week 17, 18, 26, 41, 42 (a). HON+ detects the anomaly in week 43 and 44 with one false positive after addtion of the noice (b). Correct anomalies are marked as red and false anomalies are marked as orange
