Traveltime: Earthquake traveltimes

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

Description

Calculates traveltimes between focus and receiver(s).

Usage

Traveltime(phase, delta, h, model, pscan = NULL)

Arguments

phase	Phase of arrival (such as 'P', 'SKKS', 'PKIKP', etc.)
delta	Epicentral distance (degrees)
h	Focal Depth (km)
model	Planet model
pscan	Optional: pscan produced by MakePscan.

Details

Only a single phase, h, and model may be provided, but delta may be a vector. Providing pscan can save considerable calculation time, but is specific to each phase/depth combination, so it's not commonly available.

Value

List with the following elements:

tt	vector of traveltimes (s)
p	vector of ray parameters (s/deg)
angles	vector of takeoff angles (degrees)
dists	vector of epicentral distances (degrees)
