Member Function Documentation

static void casa::MSFitsOutputAstron::getStartHA	(	Double &	startTime,
		Double &	startHA,
		const MeasurementSet &	ms,
		uInt	rownr
	)		[static, private]

Get the time and hourangle from the MS at the given row.

It uses the field-id and observation-id to calculate the hourangle.

static Table casa::MSFitsOutputAstron::handleSysCal	(	const MeasurementSet &	ms,
		const Vector< Int > &	spwids,
		Bool	isSubset
	)		[static, private]

Handle the SYSCAL table.

It skips the entries not needed and sorts it in the correct order.

static Int casa::MSFitsOutputAstron::makeIdMap	(	Block< Int > &	map,
		Vector< Int > &	selids,
		const Vector< Int > &	allids,
		Bool	isSubset
	)		[static, private]

Determine which ids are selected in the main table (used for fields and spectral-window).

It fills a block for all possible ids, where -1 tells that the id is not selected. Furthermore it fills a vector with the selected id numbers. The input is a vector containing all ids in the main table. If isSubset is False the main table is not a selection, but represents an entire MS. In that case the map and selids are simply filled with values 0-nrid.

static void casa::MSFitsOutputAstron::timeToDay	(	Int &	day,
		Double &	dayFraction,
		Double	time
	)		[static, private]

Convert time to day and fraction.

static Bool casa::MSFitsOutputAstron::writeAN	(	FitsOutput *	output,
		const MeasurementSet &	ms,
		Double	refFreq,
		Bool	writeStation
	)		[static, private]

Write the AN table.

static Bool casa::MSFitsOutputAstron::writeFitsFile	(	const String &	fitsfile,
		const MeasurementSet &	ms,
		const String &	column,
		Int	startchan = -1,
		Int	nchan = -1,
		Int	stepchan = -1,
		Bool	writeSysCal = False,
		Bool	asMultiSource = False,
		Bool	combineSpw = False,
		Bool	writeStation = False,
		Double	sensitivity = 1.0
	)		[static]

Convert a MeasurementSet to random group UVFITS, specifying the column to write ("observed", "calibrated", "model") and whether to write the system calibration table.

If asMultiSource=True a multi-source UVFits file is written.
If combineSpw=True, all spectral-windows of a frequency group are combined.

static Bool casa::MSFitsOutputAstron::writeFQ	(	FitsOutput *	output,
		const MeasurementSet &	ms,
		const Block< Int > &	spwidMap,
		Int	nrspw,
		Double	refFreq,
		Int	refPixelFreq,
		Double	chanbw,
		Bool	combineSpw
	)		[static, private]

Write the FQ table.

If combineSpw is True, all spectral-windows are written in one row of the FITS table.

static Bool casa::MSFitsOutputAstron::writeGC	(	FitsOutput *	output,
		const MeasurementSet &	ms,
		const Table &	syscal,
		const Block< Int > &	spwidMap,
		uInt	nrif,
		Bool	combineSpw,
		Double	sensitivity,
		Int	refPixelFreq,
		Double	refFreq,
		Double	chanbw
	)		[static, private]

Write the GC table.

static FitsOutput* casa::MSFitsOutputAstron::writeMain	(	Int &	refPixelFreq,
		Double &	refFreq,
		Double &	refFreq1,
		Double &	chanbw,
		const String &	outFITSFile,
		const MeasurementSet &	rawms,
		const String &	column,
		const Block< Int > &	spwidMap,
		Int	nrspw,
		Int	startchan,
		Int	nchan,
		Int	stepchan,
		const Block< Int > &	fieldidMap,
		Bool	asMultiSource,
		Bool	combineSpw
	)		[static, private]

Write the main table.

static Bool casa::MSFitsOutputAstron::writeSU	(	FitsOutput *	output,
		const MeasurementSet &	ms,
		const Block< Int > &	fieldidMap,
		Int	nrfield,
		const Block< Int > &	spwidMap,
		Int	nrspw
	)		[static, private]

Write the SU table.

static Bool casa::MSFitsOutputAstron::writeTY	(	FitsOutput *	output,
		const MeasurementSet &	ms,
		const Table &	syscal,
		const Block< Int > &	spwidMap,
		uInt	nrif,
		Bool	combineSpw
	)		[static, private]

Write the TY table.
