contPFarrivals: Contour Pickfile Arrivals

In Rquake: Seismic Hypocenter Determination

Description

Contour plot of arrival times recorded in a pickfile list.

Usage

contPFarrivals(PF, stas, proj=NULL, cont=TRUE, POINTS=TRUE, image=FALSE ,
             col=RSEIS::tomo.colors(50), gcol="black",   phase="P", add=TRUE)

Arguments

PF	Pickfile list in RSEIS format
stas	station list
proj	projection from GEOmap
cont	logical, add contour to plot
POINTS	logical, add mark up (stations) to plot
image	logical, add image to plot
col	color palette for image
gcol	color for contour lines
phase	character, phase to contour
add	logical, TRUE=add to existing plot

Details

Contours the arrival time. The earliest arrival is subtracted from each time pick. Uses only the phase indicated and there can be only one phase per station - default is earliest at each station.
