Method Detail

getComplexRpp

public Complex getComplexRpp(double rayParam)
                      throws VelocityModelException

Calculates incident P wave to reflected P wave complex coefficient at free surface. Only topVp, topVs, and topDensity are used, the bottom values are ignored. This is a little strange as free surface rays are always upgoing, but it mantains consistency with the solid-solid calculations.

= (-1*((1/sqTopVs) - 2 * sqRP)^2 +
4 * sqRP * topVertSlownessP * topVertSlownessS) / A

Specified by:

getComplexRpp in class ReflTrans

Throws:

VelocityModelException

getComplexRps

public Complex getComplexRps(double rayParam)

Calculates incident P wave to reflected SV wave complex coefficient at free surface. = (4 * (topVp/topVs) * rp * topVertSlownessP * ((1/sqTopVs) - 2 * sqRP)) / fsA

Specified by:

getComplexRps in class ReflTrans

getComplexTpp

public Complex getComplexTpp(double rayParam)
                      throws VelocityModelException

Specified by:
