“…Theory and implementation of different AR-AIC picking algorithms are described, for example, in Takanami and Kitagawa (1991), Leonard and Kennett (1999), or Sleeman and van Eck (1999). Although multivariate AR approaches appear to be slightly more appropriate for robust S-wave picking (e.g., Takanami and Kitagawa, 1993;Leonard and Kennett, 1999), the application of the univariate method to single components (N, E, Q, and T) and combined components (E N) provides additional details about uncertainty of timing and phase identification.…”

Our implementation is mainly based on the method of Takanami and Kitagawa (1988), which uses an univariate AR fitting approach to derive automatic arrival times.…”

“…Leonard and Kennett, 1999, and references therein). In the procedure, an auto-regressive (AR) model is generated for the background noise prior to the detection time and a residual trace is formed containing, for each sample, the difference between the recorded value and the linear prediction from the preceding samples using this AR-model (e.g.…”

“…Gibbons et al (2005) applied the AR-AIC (Autoregressive -Akaike Information Criterion) method (Akaike, 1973;GSE/JAPAN/40, 1992;Leonard and Kennett, 1999) and found that this provided excellent estimates for the Pn-arrivals from Kovdor events due to the large contrast in amplitudes over a wide range of frequencies. Given the limited source region of interest, and the fact that the study was limited to a single array station, Gibbons et al (2005) fixed a time-frame relative to the autoregressive Pn-arrival time estimate and measured slowness for the secondary phases in time-windows fixed relative to the Pn onset estimate.…”
