FindP4Dist: Ray Parameter for Epicentral Distance

In TauP.R: Earthquake Traveltime Calculations for 1-D Earth Models

Description

Calculates ray parameter and takeoff angle to reach given epicentral distances. Including a pscan improves speed if you already have it, but is not necessary.

Usage

FindP4Dist(phase, deltalist, h, model, pscan = NULL)

Arguments

phase	Wave arrival phase (e.g. 'P', 'SKS')
deltalist	Vector of epicentral distances (degrees)
h	Focal depth (km)
model	Planet model
pscan	Output of MakePscan

Value

List with following values:

p	Vector of ray parameters (s/deg)
a	Vector of takeoff angles (deg)
d	Vector of corresponding epicentral distances (deg)
deltain	Vector of target epicentral distances (deg)
