In RSEIS: Seismic Time Series Analysis Tools

Short-term/Long-term Average curve

Description

Get short-term average long-term verage ratio curve for picking

Usage

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

Arguments

y	signal
dt	sample rate
fwlen	forward window, number of samples
bwlen	back window length, number of samples
stretch	stretch multiplier
MED	median smoother
PLOT	logical, TRUE=plot diagnostics

Details

Uses C-code and fast tanking algorithm written at UW

Value
