Localization of AE sources

Fig 1: AE event #401 recorded at eight transducers. Example of the arrival time determination (vertical lines) using WinPecker. The detail-window in the upper right corner gives better control over the picking process. The result of the hypocenter determination (in meter) is shown in the status row at the bottom [6].
