Constructor & Destructor Documentation

casa::refim::MosaicFT::MosaicFT	(	SkyJones *	sj,
		MPosition	mloc,
		String	stokes,
		Long	cachesize,
		Int	tilesize = `16`,
		Bool	usezero = `True`,
		Bool	useDoublePrec = `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).

Construct from a Record containing the MosaicFT state.

casa::refim::MosaicFT::MosaicFT ( const MosaicFT & other )

Copy constructor.
