GAZI: Get azimuthal particle motion

In RSEIS: Seismic Time Series Analysis Tools

Get azimuthal particle motion

Description

Do particle motion analysis

Usage

GAZI(ADAT, dt = 1, ex = seq(0, 100),
comp = c(4, 5, 6), sta = "ZZZ", az = 0,
len = 50, shift = 10, prev = 1, fileid = "", picks = NA, labs = NA)

Arguments

ADAT	Matrix of 3 component seismic data
dt	delta T (s)
ex	x-axis vector
comp	component names
sta	station name
az	azimuth of station orientation
len	length of time series
shift	amount to shift per window
prev	length of buffer at beginning of trace
fileid	character string to put on plot
picks	arrival times for annotation
labs	labels for arrival times for annotation

Value

list(aex=aex[1:jall], rateig=rateig[1:jall], aaz=aaz[1:jall], ai=ai[1:jall], figaz=figaz, azpar=azpar, incpar=incpar )

Examples

data("GH")


temp  <-  cbind(GH$JSTR[[4]], GH$JSTR[[5]], GH$JSTR[[6]])

pmolabs <- c("Vertical", "North", "East")


 G   <-  GAZI(temp, dt =GH$dt[4]  , comp = pmolabs, sta = GH$STNS[4] ,
az = 0, len =75, shift = 10, prev = 1)
