modified_energy_ratio
(arr, win_len=100)[source]¶ Modified energy ratio method for arrival time estimation.
The modifications improve the ability to detect the onset of a seismic arrival in the presence of random noise.
- Parameters
- Return type
- Returns
Array with computed detection function
Index of the estimated arrival time (max value)
