FILT.SEISN: Filter Traces

In RSEIS: Seismic Time Series Analysis Tools

Filter Traces

Description

Filter Traces in a seismic structure

Usage

FILT.SEISN(TH, sel = 1:length(TH$JSTR),
FILT = list(ON = TRUE, fl = 0.5, fh = 7, type = "HP",
 proto = "BU", RM=FALSE, zp=TRUE ), TAPER = 0.1, POSTTAPER = 0.1, AUGMENT=FALSE)

Arguments

TH	Seismic structure
sel	selection of traces
FILT	filter definition
TAPER	filter taper
POSTTAPER	taper after filter
AUGMENT	Logical, FALSE

Details

RSEIS Seismic structure is filtered, trace by trace. If AUGMENT is TRUE, traces are augmented at beginning and end, filtered and then truncated to suppress edge effects. In that case no tapering is applied post fitler.

Value

RSEIS Seismic structure, traces are filtered and a proc is added to the trace history.

Examples

##   Fdef = choosfilt()
Fdef  <-  list(ON=FALSE, fl=0.5, fh=7.0, type="BP", proto="BU", RM=FALSE, zp=TRUE )
data("GH")
sel <-  which(GH$COMPS=="V")

sel  <-  1:3
 KF  <-  FILT.SEISN(GH, sel = sel, FILT=Fdef)
swig(KF, sel=sel, SHOWONLY=0)
