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)
