Constructor & Destructor Documentation

casa::Partition::Partition	(	String &	theMS,
		Table::TableOption	option = `Table::Old`
	)

casa::Partition::Partition ( MeasurementSet & ms )

construct from an MS

virtual casa::Partition::~Partition ( ) [virtual]

Member Function Documentation

Bool casa::Partition::copyDataFlagsWtSp	(	const Vector< MS::PredefinedColumns > &	colNames,
		const Bool	writeToDataCol
	)			`[private]`

This method uses VisIter for efficient copy mode data transfer.

Bool casa::Partition::doTimeAver ( const Vector< MS::PredefinedColumns > & dataColNames ) [private]

Read the input, time average it to timeBin_p, and write the output.

Bool casa::Partition::fillAccessoryMainCols ( ) [private]

Bool writeDiffSpwShape(const Vector<MS::PredefinedColumns>& colNames);.

Bool casa::Partition::fillAllTables ( const Vector< MS::PredefinedColumns > & colNames ) [private]

(Sub)table fillers.

Bool casa::Partition::fillMainTable ( const Vector< MS::PredefinedColumns > & colNames ) [private]

static void casa::Partition::getDataColMap	(	MSMainColumns *	msc,
		ArrayColumn< Complex > *	mapper,
		uInt	ntok,
		const Vector< MS::PredefinedColumns > &	colEnums
	)			`[static, private]`

Fills mapper[ntok] with a map from dataColumn indices to ArrayColumns in the output.

mapper must have ntok slots!

Bool casa::Partition::getDataColumn	(	ROArrayColumn< Float > &	data,
		const MS::PredefinedColumns	colName
	)			`[private]`

Bool casa::Partition::getDataColumn	(	ROArrayColumn< Complex > &	data,

*** Private member functions ***

Bool casa::Partition::makePartition	(	String &	outname,
		String &	whichDataCol,
		const Vector< Int > &	tileShape = `Vector< Int >(1, 0)`,
		const String &	combine = `""`
	)

void selectSource(Vector<String> sourceid);

Method to set if a phase Center rotation is needed void setPhaseCenter(Int fieldid, MDirection& newPhaseCenter);

Method to make the partition.

TileShape of size 1 can have 2 values [0], and [1] ...these are used in to determine the tileshape by using MSTileLayout. Otherwise it has to be a vector size 3 e.g [4, 15, 351] => a tile shape of 4 stokes, 15 channels 351 rows.

combine sets combine_p. (Columns to ignore while time averaging.)

virtual MeasurementSet* casa::Partition::makeScratchPartition	(	const String &	whichDataCol,
		const Bool	forceInMemory = `False`
	)			`[virtual]`

In this form whichDataCol gets passed to parseColumnNames().

virtual MeasurementSet* casa::Partition::makeScratchPartition	(	const Vector< MS::PredefinedColumns > &	whichDataCols,
		const Bool	forceInMemory = `False`
	)			`[virtual]`

Method to make a scratch partition and even in memory if posssible Useful if temporary subselection/averaging is necessary It'll be in memory if the basic output ms is less than half of memory reported by HostInfo unless forced to by user.

Bool casa::Partition::makeSelection ( ) [private]

method that returns the selected ms (?! - but it's Boolean - RR)

Double casa::Partition::n_bytes ( ) [inline, private]

		String	timerng = `""`
	)

select time parameters

void casa::Partition::setMS ( MeasurementSet & ms )

select Time and time averaging or regridding void selectTime();

select stuff using msselection syntax ...time is left out call it separately with timebin
