PSTLTcurve {RSEIS}R Documentation

Short Term/Long Term curve

Description

ST/LT ratio curve for sutomated picking routines

Usage

PSTLTcurve(y, dt = 0.008, fwlen = 125, bwlen = 125, perc = 0.05, stretch = 1000, MED = 255, PLOT = FALSE)

Arguments

y signal
dt deltaT (s)
fwlen forward window
bwlen backward window
perc percent cut-off
stretch stretch curve
MED Median smoothing parameter
PLOT logical, TRUE=PLOT

Value

list(flag=1, ind=ix, eye=eye, mix=mix, SNR=SNR, s2=s2, rat=therat)

flag flag on success
ind index of pick estimate 1
eye index of pick estimate 2
mix index of pick estimate 3
SNR Signal/Noise ratio
s2 sum squared
rat ratio curve
