pickit: Automatic Picking Algorithm

In RSEIS: Seismic Time Series Analysis Tools

Automatic Picking Algorithm

Description

Automatic Picking Algorithm

Usage

pickit(ay, deltat = 0.008, MED = 225, FRWD = 8, BKWD = 8,
 sbef = 1, saft = 6, thresh = 2, Tthresh2 = 7,
stretch = 1000, flo = 0.1, fhi = 5, Kmin = 7,
dthresh = 0.01, threshbot = 1.01)

Arguments

ay	signal
deltat	sample rate
MED	use median smoothing?
FRWD	forward window, s
BKWD	backward window
sbef	seconds before
saft	seconds after
thresh	threshold 1
Tthresh2	threshold 2
stretch	stretch factor
flo	low frequency for BP filter
fhi	low frequency for BP filter
Kmin	min number of picks per window
dthresh	delta threshold
threshbot	threshold bottom limit

Details

used internally. This code uses several methods for getting best pick.

Value

list(RAT=A$rat, x=x, ay=ay, fy=fy, deltat=deltat, J=J$J , Z=Z, a1=a1, a2=a2, thresh=thresh, Tthresh2=Tthresh2, Kmin=Kmin)
