static casacore::String casa::SynthesisUtilMethods::asComprehensibleDirectionString ( casacore::MDirection const & direction )

static

return comprehensible direction string from given MDirection object

casacore::Record casa::SynthesisUtilMethods::continuumDataPartition	(	casacore::Record &	selpars,
		const casacore::Int	npart
	)

All functions here are stand-alone, self-contained methods.

Partitioning syntax for Selection parameters

casacore::Input casacore::Record (example) : { 'ms0' : { 'msname':xxx1, 'spw':yyy }, 'ms1' : { 'msname':xxx2, 'spw':yyy } }

Output casacore::Record (example for partitioning on spw) : { '0' : { 'ms0' : { 'msname':xxx1, 'spw':yyy1 }, 'ms1' : { 'msname':xxx2, 'spw':yyy1 } } '1' : { 'ms0' : { 'msname':xxx1, 'spw':yyy2 }, 'ms1' : { 'msname':xxx2, 'spw':yyy2 } } }

static

casacore::CoordinateSystem and number of channels of original cube is passed in Output record is the ms's and data selection for each part.

also the casacore::Vector of outCsys and outnChan are the coordinatesystems and nchannel of the sub cube for each part. The image is divided in n part along spectral channel now if one of the sub cube has no match the the spw selection will have a "-1" for that part. The caller will have to deal with that for load balancing etc.. Output casacore::Record (example for partitioning on spw) : { '0' : { 'ms0' : { 'msname':xxx1, 'spw': '0:5~10' }, 'ms1' : { 'msname':xxx2, 'spw':'0:20~25' }, 'nchan': 6, 'coordsys': { A record of the coordinatesystem of subcube 0}} '1' : { 'ms0' : { 'msname':xxx1, 'spw':'0:9~14' }, 'ms1' : { 'msname':xxx2, 'spw':'0:24~29' }, 'nchan':6, 'coordsys': { A record of the coordinatesystem of subcube 1} } } the coordsys keyed record can be use in casacore::CoordinateSystem:;restore to reconstrucr it is the same as the parameter outCsys

casacore::Data partitioning rules for CUBE imaging

uniform contiguous partition in frequency step Note that the spw selection will have a "-1" if there is no overlap in the data selection provided and frequency range provided

static casacore::Int casa::SynthesisUtilMethods::validate ( const VisBuffer & vb )

static

Validate the supplied VB.

This currently only checks for the existence of at least one non-flagged row and returns the index of the first non-flagged row found. Otherwise returns SynthesisUtilMethods::NOVALIDROWS. This static method is called in the vis-iter loops to block invalid VBs from flowing down the pipes.
