FinalTvi2 - Class that serves as the final Tvi2 in a pipeline; it adds simple write functionality that allows writing back the data contained in the associated VB2.
Public interface
The FinalTvi2 in a transforming VI2 pipeline.
At the end of a Transforming VI pipeline it can be handy to write out the result. Putting a FinalTvi2 as the last transforming VI allows the output to disk of the transformed data into a brand new MS.

This method writes back any changed (dirty) components of the provided VisBuffer and is the preferred method for writing data out.

void configureNewSubchunk ();
These are the methods that actually write the data in the VB2 out to the new MS when called by writeBackChanges. The VB's data are handled as four categories: data - the various visibility data and the associated weight, weight spectrum, sigma, etc. keys - the values of the columns that ID the row (e.g., antennas, DdId, etc.) misc - the column values that don't fall in the data or key categories.
| virtual void casa::vi::FinalTvi2::writeFlag | ( | const Cube< Bool > & | flag | ) | [virtual] |
Write/modify the flags in the data.
This writes the flags as found in the MS, Cube (npol,nchan,nrow), where nrow is the number of rows in the current iteration (given by nRow ()).
Reimplemented from casa::vi::TransformingVi2.
| virtual void casa::vi::FinalTvi2::writeFlag | ( | const Matrix< Bool > & | flag | ) | [virtual] |
These methods will throw a not-implemented exception if called.
They are here because the interface requires them but the intended use of FinalTvi2 expects that the data will be output using only the writeBackChanges method.

Write/modify the ncorr x nrow SigmaMat.
virtual void writeSigmaMat (const Matrix<Float> & sigmat);
Write the information needed to generate on-the-fly model visibilities.
Reimplemented from casa::vi::TransformingVi2.
| virtual void casa::vi::FinalTvi2::writeSigma | ( | const Matrix< Float > & | sig | ) | [virtual] |
Write/modify the Sigma.
Reimplemented from casa::vi::TransformingVi2.
| virtual void casa::vi::FinalTvi2::writeVisCorrected | ( | const Cube< Complex > & | vis | ) | [virtual] |
Write/modify the visibilities.
This is possibly only for a 'reference' MS which has a new DATA column. The first axis of the matrix should equal the selected number of channels in the original MS. If the MS does not contain all polarizations, only the parallel hand polarizations are used. virtual void writeVisCorrected (const Matrix<CStokesVector> & visibilityStokes); virtual void writeVisModel (const Matrix<CStokesVector> & visibilityStokes); virtual void writeVisObserved (const Matrix<CStokesVector> & visibilityStokes);
Write/modify the visibilities This writes the data as found in the MS, Cube (npol,nchan,nrow).
