protected:

virtual void casa::SideBandSeparatorII::separate ( const std::string &  outfile, const bool  overwrite  )

virtual

invoke sideband separation

Parameters

[in]	outfile	the prefix of output file names. Suffixes which indicates sideband, i.e., 'signalband' and 'imageband', are added to outfile .
[in]	overwrite	if true overwrite existing output files. if false, an error is raised if an output file already exists.

Implements casa::SideBandSeparatorBase.

void casa::SideBandSeparatorII::setImageBandFrequency	(	const double	refpix,
		const casacore::Quantity	refval
	)

set frequency information of output image in image sideband

Parameters

[in]	refpix	reference channel of image sideband
	in'	refval frequency in reference channel
