Constructor & Destructor Documentation

casa::PBMosaicFT::PBMosaicFT	(	MeasurementSet &	ms,
		Int	nFacets,
		Long	cachesize,
		String &	cfCacheDirName,
		Bool	applyPointingOffset = `True`,
		Bool	doPBCorr = `True`,
		Int	tilesize = `16`,
		Float	paSteps = `5.0`,
		Float	pbLimit = `5e-2`,
		Bool	usezero = `False`
	)

Constructor: cachesize is the size of the cache in words (e.g.

a few million is a good number), tilesize is the size of the tile used in gridding (cannot be less than 12, 16 works in most cases).

casa::PBMosaicFT::PBMosaicFT ( const RecordInterface & stateRec )

Construct from a Record containing the PBMosaicFT state.
