Volcanic Pulse Analysis

Description

given a seiries of pulses, do analysis on each one

Usage

tung.pulse(r, q, dt)

Arguments

r x-coordinates
q y-coordinates
dt deltat, sample interval

Details

Calculates, min, max of edges and center, then models the pulse with a triangular pulse and integegrates.

Value

vector=c(Ex[1], Ex[2], Ey[1], Ey[2], Cx, Cy, ar2, DefInt[1], DefInt[2], sum0) where:

Ex left minimum
Ey right minimum
Cx, Cy center (max?)
ar2 area of triangle
DefInt[1] integral under curve
DefInt[2] integral under curve ( bottom triangle removed)
sum0 RMS amplitude
