pickit: 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

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)

Details

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