CalcXP: Calculate Horizontal Travel

Description

Calculates horizontal travel within a single layer.

Usage

CalcXP(p, v, z, zmin, zmax, novertex)

Arguments

p

Ray Parameter (s/deg)

v

Velocity at top and bottom of layer (km/s)

z

Depth at top and bottom of layer (km)

zmin

Minimum allowed depth (km)

zmax

Maximum allowed depth (km)

novertex

Block handling of vertices if TRUE.

Value

• Horizontal distance traveled in layer in flat earth coordinates.

Details

All depths and velocities must be flat earth transformed. This is a subordinate routine for CalcXPsum. Regrettably, this is not vectorized; this will be corrected in later editions.

Examples

#### Not a user routine: subordinate to CalcXPsum.
