Etymology

This class contains the type definitions in the ComponentModels module

Synopsis

This class does nothing. It is merely a container for the enumerations used by the ComponentModels module. These enumerations define the standard component types. It also contains:

The first element in the enumerator must be represented by zero and every enumerator must contain as the second last and last elements an UNKNOWN_* and NUMBER_* element.

Example

See the documentation for the ComponentModels classes for examples on the use of these enumerator and functions. For example the ComponentShape class.

To Do

Definition at line 92 of file ComponentType.h.

Member Enumeration Documentation

The ways the Flux polarisation can be represented.

Enumerator
STOKES 

The four casacore::Stokes parameters, ie I,Q,U,V.

LINEAR 

Linear polarisation feeds ie., XX,XY,YX,YY with zero parrallactic angle.

CIRCULAR 

Circular polarisation feeds ie., RR, RL, LR, LL.

UNKNOWN_POLARISATION 

An unknown Component.

NUMBER_POLARISATIONS 

The number of types in this enumerator.

Definition at line 116 of file ComponentType.h.

The shapes of all the components.

Enumerator
POINT 

A simple point component.

GAUSSIAN 

A elliptical Gaussian component.

DISK 

A elliptical disk component.

LDISK 

A elliptical disk component with limb-darkening effect.

UNKNOWN_SHAPE 

An unknown Component.

NUMBER_SHAPES 

The number of types in this enumerator.

Definition at line 101 of file ComponentType.h.

The different functional forms for the spectral variation.

Enumerator
CONSTANT_SPECTRUM 

The flux is constant at different frequencies.

SPECTRAL_INDEX 

The flux varies as I = I_0 * (nu / nu_0)^alpha

TABULAR_SPECTRUM 

Tabular values interpolated in between.

UNKNOWN_SPECTRAL_SHAPE 

an unknown spectral type

NUMBER_SPECTRAL_SHAPES 

The number of spectral types in this enumerator.

Definition at line 129 of file ComponentType.h.

Member Function Documentation

static ComponentShape* casa::ComponentType::construct ( ComponentType::Shape  shapeEnum)
staticprivate

Convert the Shape enumerator to a shape object (upcast to the base object).

Returns a null pointer if the object could not be constructed. This will occur is the enumerator is UNKNOWN_SHAPE or NUMBER_SHAPES or there is insufficient memory. The caller of this function is responsible for deleting the pointer.

static SpectralModel* casa::ComponentType::construct ( ComponentType::SpectralShape  spectralEnum)
staticprivate

Convert the SpectralShape enumerator to a spectral model object (upcast to the base object).

Returns a null pointer if the object could not be constructed. This will occur is the enumerator is UNKNOWN_SPECTRAL_SHAPE or NUMBER_SPECTRAL_SHAPES or there is insufficient memory. The caller of this function is responsible for deleting the pointer.

static casacore::String casa::ComponentType::name ( ComponentType::Shape  shapeEnum)
static

Convert the Shape enumerator to a string.

static casacore::String casa::ComponentType::name ( ComponentType::Polarisation  fluxEnum)
static

Convert the Polarisation enumerator to a string.

static casacore::String casa::ComponentType::name ( ComponentType::SpectralShape  spectralEnum)
static

Convert the SpectralShape enumerator to a string.

static ComponentType::Polarisation casa::ComponentType::polarisation ( const casacore::String polarisationName)
static

Convert a given casacore::String to a Polarisation enumerator.

static ComponentType::Shape casa::ComponentType::shape ( const casacore::String shapeName)
static

Convert a given casacore::String to a Shape enumerator (min match active)

Referenced by casa::PeakIntensityFluxDensityConverter< T >::setShape().

static ComponentType::SpectralShape casa::ComponentType::spectralShape ( const casacore::String spectralName)
static

Convert a given casacore::String to a SpectralShape enumerator.
