static void casa::ConverterIntensity::convert	(	Vector< float > &	values,
		const Vector< float >	hertzValues,
		const QString &	oldUnits,
		const QString &	newUnits,

		const QString &	maxUnits
	)		[static]

Hertz values are needed corresponding to the values for Jy/Beam Kelvin conversions only.

Both oldUnits and newUnits refer to the old and new units of the values array. In order to do FRACTION_OF_PEAK conversions, a maximum value with corresponding maximum units must be passed in.
