SlownessLayer
public SlownessLayer(VelocityLayer vLayer, boolean spherical, double radiusOfEarth, boolean isPWave)Compute the slowness layer from a velocity layer. -
SlownessLayer
Compute the slowness layer from a velocity layer. Since radiusOfEarth is given we assume a spherical model. -
SlownessLayer
Compute the slowness layer from a velocity layer. Since radiusOfEarth is not given we assume a flat model.

evaluateAt_bullen
Finds the slowness at the given depth. radiusOfEarth is needed as a slowness layer doesn't have access to the slowness model. Note that this method assumes a Bullen type of slowness interpolation, ie p(r) = a*r^b. This will produce results consistent with a tau model that uses this interpolant, but it may differ slightly from going directly to the velocity model. Also, if the tau model is generated using another interpolant, linear for instance, then the result may not be consistent with the tau model.- Throws:
SlownessModelException
-
bullenRadialSlowness
public TimeDist bullenRadialSlowness(double p, double radiusOfEarth, boolean downgoing) throws SlownessModelExceptionCalculates the time and distance (in radians) increments accumulated by a ray of spherical ray parameter p when passing through this layer. Note that this gives 1/2 of the true range and time increments since there will be both an up going and a downgoing path. Here we use the Mohorovicic or Bullen law p=A*r^B- Throws:
SlownessModelException
- occurs if the calculated distance or time increments are negative or NaN, this indicates a bug in the code (and hopefully will never happen).
-
bullenDepthFor
Finds the depth for a ray parameter within this layer. Uses a Bullen interpolant, Ar^B. Special case for botP == 0 or botDepth == radiusOfEarth as these cause div by 0, use linear interpolation in this case.- Throws:
SlownessModelException
