WASEM separation of the observed space-time diagram SDO/AIA 304Å ((a)) with selected time series at Y = 138″and wavelet power spectrum. Part b: averaged global wavelet spectrum AGWS with L1 − L2 limits. Separated space-time diagrams according to period range PR1 − PR4 (PR3 and PR4 with the tadpole wave and the plasma flow propagation, respectively). Global wavelet spectrum (GWS) determined a characteristic period Pch above the global 95% significance level curve. WASEM analysis validity tests (part c).
