	)

static

static casacore::Vector<casacore::String> casa::MSUtil::getSpectralFrames	(	casacore::Vector< casacore::MFrequency::Types > &	types,
		const casacore::MeasurementSet &	ms
	)

static

Return all the selected SPW types selected in the selected casacore::MS if the input ms is a reference MS.

Else it will return all the types in the SPW table

		const casacore::Int	fieldId = `0`
	)

static

This method gives you the channels (and spws) that will cover the freq range provided in the frame the user stated.

The conversion from the data frame will be done properly for finding this spw, start, nchan will be resized appropriately

static void casa::MSUtil::getSpwInFreqRangeAllFields	(	casacore::Vector< casacore::Int > &	spw,
		casacore::Vector< casacore::Int > &	start,
