Constructor Details

ProfileFeatureCell

public ProfileFeatureCell(String name,
 DataReference buoyProfileRef)
                   throws VisADException,
RemoteException

Constructs from data references. The input buoyancy profile must be ascending.

Parameters:

name - The name of the cell.

buoyProfileRef - The input buoyancy profile reference.

Throws:

VisADException - if a VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.

Method Details

interpolatePres

protected static final Real interpolatePres(double topPres,
 double topBuoy,
 double botPres,
 double botBuoy,
 Unit presUnit)
                                     throws VisADException

Interpolates the pressure at zero buoyancy from bracketing pressures and buoyancies. The buoyancies must not have the same sign.

Parameters:

topPres - The upper pressure.

topBuoy - The buoyancy at the upper pressure.

botPres - The lower pressure.

botBuoy - The buoyancy at the lower pressure.

presUnit - The unit of pressure.

Returns:

The interpolated pressure at zero buoyancy.

Throws:

VisADException - if a VisAD failure occurs.
