Fig. 5From: Improvement of back-azimuth estimation in real-time by using a single station recordComparison between the conventional fixed time window and the new variable time window. In the new approach, the length from a P-wave arrival to the first zero-cross point (first half cycle of the wavelength of the initial P-wave) of the UD component of the band-pass displacement data is adopted as the time window.Back to article page
