Prerequisite

• General knowledge of FITS binary and ASCII tables.

Etymology

Synopsis

Like FITSTableWriter except that this must be the first HDU and all "columns" in the description must have the same type, i.e. float.

Constructor & Destructor Documentation

casacore::FITSGroupWriter::FITSGroupWriter	(	const String &	fileName,
		const RecordDesc &	description,
		uInt	nrows,
		const Record &	extraKeywords,
		Bool	freeOutput = True
	)

Since this must always be the first HDU, there is no point in constructing it with a FitsOutput.

description indicates the names of the random groups parameters. nrows is a synonym for ngroups. Use extraKeywords to indicate any keywords not automatically created (SIMPLE, BITPIX, NAXIS*, EXTEND, BLOCKED, GROUPS, PCOUNT, GOUNT, ORIGIN, END). If freeOutput is True, file will be deleted by the destructor. You might not want this to happen if you are going to write any extensions to the same fits file. You can get the FitsOutput used here from write()
