PICK.GEN {RSEIS}R Documentation

Seismic Analysis

Description

Main Interactive Program for plotting and analyzing seismic waveform data.

Usage

PICK.GEN(GH, sel = 1:length(GH$dt), ORD = NULL, WIN = NULL, APIX = NULL,
PHASE = NULL,
STDLAB = NULL, PADDLAB = NULL, TEMPBUT=NULL,
SHOWONLY = FALSE, CHOP = FALSE, TIT = "",
pts = FALSE, forcepix = FALSE, SCALE = 1,
velfile = "", stafile = "", LOC = NULL,
FILT=list(fl=.2, fh=15,  type="HP", proto="BU"), filters=NULL)

Arguments

GH Seismic data structure
sel selection of traces from structure
ORD order to plot traces
WIN vector c(t1, t2) for window of traces to be shown
APIX structure of arrival time picks
PHASE phase to display, "P", "S", etc
STDLAB label of buttons
PADDLAB label of phase-pick buttons
TEMPBUT temporary, user defined buttons
SHOWONLY logical, TRUE=non-interactive
CHOP whether to chop the signal
TIT title for the top of plot
pts whether to plot specific points on the plot
forcepix logical, force all phase picks to be shown on all traces
SCALE flag, 1,0= scale according to window or trace
velfile velocity structure or file name
stafile station structure or file name
LOC source location structure (lat, lon, depth)
FILT default filter definition list(fl=.2, fh=15, type="HP", proto="BU")
filters a list of filters for choosfilt

Details

This is the main program that drives the other analysis in RSEIS. GH is a list consisting of header (meta-data) and time series information. See documentation on GH to get complete description.

A set of filters can be defined by the user, see choosfilt

Default Buttons, can be created by: STDLAB = c("DONE", "QUIT","zoom out", "zoom in", "Left", "Right", "restore", "Pinfo","WINFO", "XTR", "SPEC", "SGRAM" ,"WLET", "FILT", "UNFILT", "SCALE", "Postscript")

Value

Various strucutres are returned based on interactive selections of the user.
Howeverr, the default return list:

but last button pushed
sloc location of last set of clicks
WPX set of saved WPIX (window picks
BRUNINFO Brune Model information
DETLINFO Detailed information about traces
mark mark (MARK button was pressed
PUSHED list of all buttons pressed prior to exit

Examples

data("GH")
###  This loads a structure

  STDLAB = c("DONE", "QUIT","zoom out", "zoom in", "Left", "Right", "restore", "Pinfo","WINFO",
                           "XTR", "SPEC", "SGRAM" ,"WLET", "FILT", "UNFILT", "SCALE", "Postscript")

sel=GH$COMPS=="V" 
p = PICK.GEN(GH, sel=sel, STDLAB=STDLAB)
print(p)

 p = PICK.GEN(GH, sel=sel, WIN=c(4,14) , STDLAB=c("DONE", "LAME", "DAME"))
print(p)
