In RSEIS: Seismic Time Series Analysis Tools

Auto-Regressive AIC estimate of arrival time

Description

Auto-Regressive AIC for arrival estimate, signal detection

Usage

GETARAIC(z4, DT = 0.008, Mar = 8, O1 = 2, O2 = 0.2, WW = 2, T1 = 1, PLOT = FALSE)

Arguments

z4	signal time series
DT	sample rate,s
Mar	AR Model Order
O1	window before, s
O2	window after, s
WW	window length, s
T1	initial guess, number of samples from beginning of trace
PLOT	logical, TRUE =plot

Details

Method of Sleeman for automatic phase determination.

Value

Taic	Arrival time of wave

Examples

data(CE1)
plot(CE1$x, CE1$y, type='l')

Xamp = CE1$y[CE1$x>4.443754 & CE1$x<6.615951]
Mar=8
z4 = Xamp
DT = CE1$dt
 T1 = 50

O1 = 10*DT
O2 =  10*DT
WW = 10*DT
Nz4 = length(z4)


 araict = GETARAIC(Xamp, DT=CE1$dt, Mar=8, T1=T1, O1=O1, O2=O2, WW=WW,   PLOT=TRUE)
