Detailed Description

Function Documentation

read_Healpix_map_from_fits() [1/4]

template<typename T >

void read_Healpix_map_from_fits	(	fitshandle &	inp,
		Healpix_Map< T > &	map,
		int	colnum = 1
	)

Reads the map stored in column colnum of the FITS binary table pointed to by inp into map.

Definition at line 60 of file healpix_map_fitsio.cc.

read_Healpix_map_from_fits() [2/4]

template<typename T >

Healpix_Map<T> read_Healpix_map_from_fits	(	fitshandle &	inp,
		int	colnum = 1
	)

Returns the map stored in column colnum of the FITS binary table pointed to by inp.

Definition at line 79 of file healpix_map_fitsio.cc.

read_Healpix_map_from_fits() [3/4]

template<typename T >

void read_Healpix_map_from_fits	(	const std::string &	filename,
		Healpix_Map< T > &	map,
		int	colnum = 1,
		int	hdunum = 2
	)

Opens the FITS file filename, jumps to the HDU hdunum, and reads the column colnum into map.

read_Healpix_map_from_fits() [4/4]

template<typename T >

Healpix_Map<T> read_Healpix_map_from_fits	(	const std::string &	filename,
		int	colnum = 1,
		int	hdunum = 2
	)

Opens the FITS file filename, jumps to the HDU hdunum, and returns the map in column colnum.

prepare_Healpix_fitsmap()

void prepare_Healpix_fitsmap	(	fitshandle &	out,
		const Healpix_Base &	base,
		PDT	datatype,
		const arr< std::string > &	colname
	)

Inserts a new binary table into out, which contains one column of Planck type datatype with the name name, and writes all HEALPix specific keywords based on the information in base.

write_Healpix_map_to_fits() [1/4]

template<typename T >

void write_Healpix_map_to_fits	(	fitshandle &	out,
		const Healpix_Map< T > &	map,
		PDT	datatype
	)

Inserts a new binary table into out, which contains one column of Planck type datatype, and stores map into this column.

Definition at line 194 of file healpix_map_fitsio.cc.

write_Healpix_map_to_fits() [2/4]

template<typename T >

void write_Healpix_map_to_fits	(	fitshandle &	out,
		const Healpix_Map< T > &	mapT,
		const Healpix_Map< T > &	mapQ,
		const Healpix_Map< T > &	mapU,
		PDT	datatype
	)

Inserts a new binary table into out, which contains three columns of Planck type datatype, and stores mapT, mapQ and mapU into these columns.

Definition at line 211 of file healpix_map_fitsio.cc.

write_Healpix_map_to_fits() [3/4]

template<typename T >

void write_Healpix_map_to_fits ( const std::string &  outfile, const Healpix_Map< T > &  map, PDT  datatype  )

inline

Creates a new FITS file with the name outfile, with a binary table in HDU 2, which contains one column of Planck type datatype, and stores map into this column.

Definition at line 93 of file healpix_map_fitsio.h.

write_Healpix_map_to_fits() [4/4]

template<typename T >

void write_Healpix_map_to_fits ( const std::string &  outfile, const Healpix_Map< T > &  mapT, const Healpix_Map< T > &  mapQ, const Healpix_Map< T > &  mapU, PDT  datatype  )

inline

Creates a new FITS file with the name outfile, with a binary table in HDU 2, which contains three columns of Planck type datatype, and stores mapT, mapQ and mapU into this column.
