ConvAng2p: Angle to Ray Parameter

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

Description

Convert between ray angle (from vertical) and ray parameter.

Usage

ConvAng2p(phase, h, angle, model = NULL, vp = NULL, vs = NULL, rp =
NULL)
ConvP2Ang(phase, h, p, model = NULL, vp = NULL, vs = NULL, rp = NULL)

Arguments

phase	Arrival phase (e.g. 'P' or 'SKS')
h	Depth (km) at which to convert.
angle	Takeoff angle (degrees). 0 is downward, 180 is upward
p	Ray parameter (s/deg)
model	Planet model
vp	P wave velocity at depth h (km/s)
vs	S wave velocity at depth h (km/s)
rp	Planet radius (km)

Details

Either 'model' or all of 'vp', 'vs', 'rp' must be provided. p and angle may be vectors; other arguments may not.

Value

For ConvAng2p, returns a vector of ray parameters (s/deg) corresponding to values in 'angle'.

For ConvP2Ang, returns a vector twice the length of 'p', with all upward angles corresponding to 'p' followed by all downward angles.
