Method Details
-
toSlowness
Returns the slowness for a velocity at a depth.- Specified by:
toSlowness
in classSlownessModel
- Throws:
SlownessModelException
- if velocity is zero.
-
toVelocity
Returns the velocity for a slowness at a depth.- Specified by:
toVelocity
in classSlownessModel
- Throws:
SlownessModelException
- if slowness is zero.
-
toSlownessLayer
public SlownessLayer toSlownessLayer(VelocityLayer vLayer, boolean isPWave) throws SlownessModelExceptionConverts a velocity layer into a slowness layer.- Specified by:
toSlownessLayer
in classSlownessModel
- Throws:
SlownessModelException
- if velocity layer is malformed.
-
interpolate
public double interpolate(double p, double topVelocity, double topDepth, double slope) throws SlownessModelExceptionReturns the depth for a slowness given a velocity gradient.- Specified by:
interpolate
in classSlownessModel
- Throws:
SlownessModelException
- if the velocity gradient exactly balances the spherical decrease in slowness.
-
layerTimeDist
public TimeDist layerTimeDist(double sphericalRayParam, int layerNum, boolean isPWave, boolean downgoing) throws SlownessModelExceptionCalculates the time and distance increments accumulated by a ray of spherical ray parameter p when passing through layer layerNum. for the easy cases of zero ray parameter, the center of the earth, and constant velocity layers. 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.- Specified by:
layerTimeDist
in classSlownessModel
- Throws:
SlownessModelException
- occurs if the ray with the given spherical ray parameter cannot propagate within this layer, or if the ray turns within this layer but not at the bottom.
-
layerTimeDistAllowTurn
public TimeDist layerTimeDistAllowTurn(double sphericalRayParam, int layerNum, boolean isPWave, boolean downgoing) throws SlownessModelException- Specified by:
layerTimeDistAllowTurn
in classSlownessModel
- Throws:
SlownessModelException
-
validate
Performs consistency check on the velocity model.- Overrides:
validate
in classSlownessModel
- Returns:
- true if successful, throws SlownessModelException otherwise.
- Throws:
SlownessModelException
- if any check fails
-
toString
public java.lang.String toString()- Overrides:
toString
in classSlownessModel
