Detailed Description

VisBuffers encapulsate one chunk of visibility data for processing.

Intended use:

Public interface

Prerequisite

• VisSet
• VisibilityIterator

Etymology

VisBuffer is a buffer for visibility data

Synopsis

This class contains 'one iteration' of the VisibilityIterator It is a modifiable buffer of values to which calibration and averaging can be applied. This allows processing of the data in larger blocks, avoiding some overheads for processing per visibility point or spectrum.

See MeasurementEquations for more details on how the VisBuffer is to be used.

To Do

• reconcile vis/visCube usage: visCube, flagCube and weightMatrix are currently only correct when this VisBuffer got them from a VisIter, operations like -=, freqAverage() are only done for visibility() and flag().

Copying methods

These methods allow copying portions of the data between two VisBuffers. Because of the complicated semantics of a VisBuffer the assignment and copy-construction methods are not used as they are likely to confuse VisBuffer users.

Frequency reporting methods.

These methods provide information about the frequencies returned in the visibility cubes. The information can returned as the channel numbers (numbered as in the underlying MS data) or in a frame-based frequency. This information reported need not be in the same frame of reference used to select the data. If the frame of reference is specified in the call, then that is the frame that is used to calculate the frequencies. If it is not specified, then the VisibilityIterator will be queried for virtual the reportingFrame; if the user has specified a reporting frame to the virtual VI then that frame will be used; otherwise the frame used to select the frequencies will be used. If the user provides no frequency selection to the VI then the selection frame will TOPO.

Both the channelNumber and frequency reporting methods come in two versions: one returns a single frequency for the specified frequency index and row while the other provides all of the frequencies for the specified row. The frequency index is the zero-based index along the frequency axis of a visibility cube.

virtual const Matrix<Float>& casa::vi::VisBufferWrapperAsync2::imagingWeight

Subhchunk information methods

These methods provide information related to the current subchunk. The isNewXXX methods return True if the XXX property of the subchunk differs from the previous subchunk.

The methods msId and msName provide information about the MS related to the current subchunk. The msID is the zero-based index of the MS in the sequence of MSs being iterated over.

The isWritable method is True when the attached iterator is writable and False otherwise.

The isRekeyable method is True when the VisBuffer is writable and also allows the modification of non-data fields (e.g., antenna1, fieldId, etc.) A rekeyable VB is one that could be used to create data for a brand new MS.

(

)

const [virtual]

Returns the number of correlations along the visCube correlation axis.

Implements casa::vi::VisBuffer2.

virtual void casa::vi::VisBufferWrapperAsync2::normalize

(

)

[virtual]

Sort/unsort the correlations, if necessary (Rudimentary handling of non-canonically sorted correlations--use with care!)

The sorting functionality is a horrible kluge that puts the VisBuffer into a somewhat incoherent state (e.g., after sorting the correlation types array does not correspond to the data) and appears to serve the needs of a tiny piece of code. As such, this refactor is initially not going to support this functionality since it is probably better implemented in the one place that actually needs it. (jjacobs 10/3/12)

virtual void sortCorr (); virtual void unSortCorr();

Normalize the visCube by the modelVisCube.

Implements casa::vi::VisBuffer2.

(

)

[virtual]

Set the weight cube using the sigma cube.

Each weight will be the reciprocal of the square of the corresponding element in the model VisCube multiplied by the number of channels in the spectral window. If an element in sigma is zero then the corresponding weight element will also be set to zero.

Dirty component methods

The dirtyComponent methods support the data-flow approach to using VisBuffers (the Visibility Processing Framework). In this approach a VisBuffer is passed to successive processing nodes (e.g., applycal, flagging, etc.) which operate on it and pass it on to the next node in the algorithm. The dirtyComponents mechanism allows a processing node to mark portions of the VisBuffer as modified. If the VisBuffer reaches an write-to-disk node then the modified portions of the VisBuffer will be written out. The user can also explicitly direct that the changes be written out using the writeChangesBack method.

Using a setter on a VisBuffer component will also set the dirty flag for that component. Normally the user should not need to use these methods; however, they are available in case unexpected situations should arise in the future.
