TauP.R (version 1.0)

Traveltime: Earthquake traveltimes

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.

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)

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.
