Constructor & Destructor Documentation

casa::GridBoth::GridBoth	(	SkyJones &	sj,
		Long	cachesize,
		Int	tilesize,
		String	sdConvType = "BOX",
		String	synConvType = "SF",
		Float	padding = 1.0,
		Float	sdScale = 1.0,
		Float	sdWeight = 1.0
	)

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), and convType is the type of gridding used (SF is prolate spheriodal wavefunction, and BOX is plain box-car summation). mLocation is the position to be used in some phase rotations. If mTangent is specified then the uvw rotation is done for that location iso the image center.
