Construct from a MeasurementSet, with iteration order specified in columns (giving the MS enum for the column) Specify channel selection as a Matrix(3,nSpw) where for each spectral window the three values are start,nChannel and spectral window number.
Spectral windows without an entry will have all channels selected. Specify a time interval for iterating in 'chunks' of time. The default time interval of 0 groups all times together. This constructor creates three new columns: MODEL_DATA and CORRECTED_DATA and IMAGING_WEIGHT If they already exist and have the same channel selection applied, they are reused. Note that the contents of these columns are NOT initialized, you should fill them before trying to read the data. The MS calibration scratch columns can be optionally compressed.

| const Block< Matrix< Int > > & | chanSelections, | |||
| Double | timeInterval = 0, |
|||

This is a constructor for multiple MS.
\..but everything is same as the one above
| casa::VisSet::VisSet | ( | MeasurementSet & | ms, | |
| const Matrix< Int > & | chanSelection, | |||
| Double | timeInterval = 0 | |||
| ) |
This is a no frills constructor, no re-sorting, the default order is used, no scratch columns is made even if they don't exist.
So if you use this constructor and plan to use the scratch columns make sure that they exist prior to constructing the VisSet this way.
Construct from an existing VisSet, this references the underlying MeasurementSet(s) but allows a new iteration order and time interval to be specified.
| casa::VisSet::~VisSet | ( | ) |
Destructor, flushes the data to disk.
Re-initialize the VisibilityIterator (cf copy ctor).
| void casa::VisSet::initCalSet | ( | Int | calSet = 0 |
) |
Initializes scratch columns.
| void casa::VisSet::flush | ( | ) |
Flushes the data to disk.
| VisIter& casa::VisSet::iter | ( | ) |
Iterator access to the data.
| void casa::VisSet::selectChannel | ( | Int | nGroup, | |
| Int | start, | |||
| Int | width, | |||
| Int | increment, | |||
| Int | spectralWindow | |||
| ) |
Reset the channel selection.
Only subsets of the original selection (set in constructor) can be specified. Note: this calls origin on the iterator.

| Int | start, | |||
| Int | width, | |||
| Int | increment, | |||

Optionally compress these columns using the CompressComplex column engine.
