+----edu.sc.seis.TauP.SphericalSModel
- public class SphericalSModel
- extends SlownessModel
This class provides storage and methods for generating slowness-depth
pairs in a spherical earth model.
-
SphericalSModel()
-
-
clone()
-
-
interpolate(double, double, double, double)
- Returns the depth for a slowness given a velocity gradient.
-
layerTimeDist(double, int, boolean)
- Calculates the time and distance increments accumulated by a
ray of spherical ray parameter p when passing through layer layerNum.
-
main(String[])
- Just for debugging purposes.
-
toSlowness(double, double)
- Returns the slowness for a velocity at a depth.
-
toSlownessLayer(VelocityLayer, boolean)
- Converts a velocity layer into a slowness layer.
-
toString()
-
-
toVelocity(double, double)
- Returns the velocity for a slowness at a depth.
-
validate()
- Performs consistency check on the velocity model.
SphericalSModel
public SphericalSModel()
main
public static void main(String args[])
- Just for debugging purposes.
toSlowness
public double toSlowness(double velocity,
double depth) throws SlownessModelException
- Returns the slowness for a velocity at a depth.
- Throws: SlownessModelException
- if velocity is zero.
- Overrides:
- toSlowness in class SlownessModel
toVelocity
public double toVelocity(double slowness,
double depth) throws SlownessModelException
- Returns the velocity for a slowness at a depth.
- Throws: SlownessModelException
- if slowness is zero.
- Overrides:
- toVelocity in class SlownessModel
toSlownessLayer
public SlownessLayer toSlownessLayer(VelocityLayer vLayer,
boolean isPWave) throws SlownessModelException
- Converts a velocity layer into a slowness layer.
- Throws: SlownessModelException
- if velocity layer is malformed.
- Overrides:
- toSlownessLayer in class SlownessModel
interpolate
public double interpolate(double p,
double topVelocity,
double topDepth,
double slope) throws SlownessModelException
- Returns the depth for a slowness given a velocity gradient.
- Throws: SlownessModelException
- if the velocity gradient
exactly balances the spherical decrease in slowness.
- Overrides:
- interpolate in class SlownessModel
layerTimeDist
public TimeDist layerTimeDist(double sphericalRayParam,
int layerNum,
boolean isPWave) throws SlownessModelException
- Calculates 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.
- 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.
- Overrides:
- layerTimeDist in class SlownessModel
validate
public boolean validate() throws SlownessModelException
- Performs consistency check on the velocity model.
- Returns:
- true if successful, throws SlownessModelException otherwise.
- Throws: SlownessModelException
- if any check fails
- Overrides:
- validate in class SlownessModel
clone
public Object clone()
- Overrides:
- clone in class SlownessModel
toString
public String toString()
- Overrides:
- toString in class SlownessModel
