Constructor & Destructor Documentation

VLAContinuumRecord::VLAContinuumRecord ( )

The default constructor creates a unusable object.

Use the attach function to turn an object constructed this way into a usable object.

VLAContinuumRecord::VLAContinuumRecord	(	ByteSource &	record,
		uInt	offset
	)

Initialise this ContinuumRecord from the given record with the specified offset.

virtual VLAContinuumRecord::~VLAContinuumRecord ( ) [virtual]

The destructor is trivial.

VLAContinuumRecord::VLAContinuumRecord ( const VLAContinuumRecord & other ) [private]

Member Function Documentation

virtual uInt VLAContinuumRecord::ant1 ( ) const [virtual]

returns the antenna 1 index for this baseline.

Implements VLABaselineRecord.

virtual uInt VLAContinuumRecord::ant2 ( ) const [virtual]

returns the antenna 2 index for this baseline.

Implements VLABaselineRecord.

void VLAContinuumRecord::attach	(	ByteSource &	record,
		uInt	offset
	)

Initialise this VLAContinuumRecord from the given BytesSource (which must contain a VLA logical record), and must be readable & seekable.

The offset specifies where the record starts.

Reimplemented from VLABaselineRecord.

virtual Vector<Complex> VLAContinuumRecord::data ( ) const [virtual]

returns the correlations for this baseline.

This will be a Vector with four elements containing the AA, CC, AC & CA (or BB, DD, BD, DB) correlations (ie all four polarisations). The returned Vector has been scaled.

Reimplemented from VLABaselineRecord.

virtual void VLAContinuumRecord::data ( Array< Complex > & values ) const [virtual]

Returns the correlations for this baseline in the supplied Array.

The supplied Array may have any number of dimensions, but all except one must have a length on 1. The axis that is not of length one must be the right length to hold all the data contained in the record. Alternatively the Array may contain no elements in which case it will be resized to a Vector of the correct length. The returned values have been scaled.

The returned Array has four elements containing the AA, CC, AC & CA (or BB, DD, BD, DB) correlations (ie all four polarisations).

Implements VLABaselineRecord.

virtual Vector<Bool> VLAContinuumRecord::flags ( ) const [virtual]

returns the flags for the correlations for this baseline.

The returned Vector will always have a length of four.

Implements VLABaselineRecord.
