MakePscan: Find Distance of p Function

Description

Constructs a distance for ray parameter function for the range of relevant ray parameters for a given phase.

Usage

MakePscan(phase, h, imodel)

Arguments

phase

Earthquake wave arrival phase (e.g. 'P', 'SKKS')

h

Focal depth (km)

imodel

Planet model returned by ImproveModel

Value

• List with following elements:
• phase
  Arrival phase
• h
  Focal depth (km)
• angles
  Takeoff angles (degrees)
• p
  Corresponding ray parameters (s/deg)
• dist
  Corresponding epicentral distances (degrees)
• vp
  P wave velocity at focus
• vs
  S wave velocity at focus
• starts
  Starting indices of intervals ( 1:(length(p) - 1) )
• ends
  Ending indices of intervals ( 2:length(p) )

Examples

data(model)

phase = 'P'
h = 100
imodel = ImproveModel(model)$newmodel
