Constructor & Destructor Documentation

casa::VisBufferUtil::VisBufferUtil ( )

Empty Constructor.

casa::VisBufferUtil::VisBufferUtil ( const VisBuffer & vb )

Construct from a VisBuffer (sets a MeasFrame)

void casa::VisBufferUtil::convertFrequency	(	Vector< Double > &	outFreq,
		const VisBuffer &	vb,
		const MFrequency::Types	freqFrame
	)

Converts the frequency in this visbuffer to the frame requested.

Bool casa::VisBufferUtil::interpolateFrequency	(	Cube< Complex > &	data,
		Cube< Bool > &	flags,
		const VisBuffer &	vb,
		const Vector< Float > &	outFreqGrid,
		const MS::PredefinedColumns	whichCol = `MS::DATA`,
		const MFrequency::Types	freqFrame = `MFrequency::LSRK`,
		const InterpolateArray1D< Float, Complex >::InterpolationMethod	interp = `(InterpolateArray1D< Float, Complex >::nearestNeighbour)`
	)

Regrid the data on a new frequency grid (defined by outFreqGrid) , on the frequency frame (defined by freqFrame).

It will pass back the interpolated data and flags

void casa::VisBufferUtil::makePSFVisBuffer ( VisBuffer & vb )

Make PSF VisBuffer.

void casa::VisBufferUtil::swapyz	(	Cube< Bool > &	out,
		const Cube< Bool > &	in
	)		`[private]`

void casa::VisBufferUtil::swapyz	(	Cube< Complex > &	out,
		const Cube< Complex > &	in
	)		`[private]`

void casa::VisBufferUtil::toVelocity	(	Vector< Double > &	outVel,
		const VisBuffer &	vb,
		const MFrequency::Types	freqFrame,
		const MVFrequency	restFreq,
		const MDoppler::Types	veldef
	)

Converts the frequency in this VisBuffer to velocity in the frame/def requested.

A MeasFrame for conversions.
