Table 5 Comparing the detection results of STA/LTA with A6-DFMSD. Parameters of both methods are adjusted for detecting DLF events. Set A: detections by at least five out of eight chosen stations, set B: detections by at least six out of eight chosen stations, set A´: detections by at least six out of 14 available stations, set B´: detections by at least seven out of 14 available stations
