template<typename T>

void create_alm	(	const PowSpec &	powspec,
		Alm< xcomplex< T > > &	alm,
		planck_rng &	rng
	)			`[inline]`

Creates a Gaussian realisation of the input power spectrum powspec, using the random number generator rng, and returns the result in alm.

Definition at line 42 of file alm_powspec_tools.cc.

template<typename T>

void create_alm_pol	(	const PowSpec &	powspec,
		Alm< xcomplex< T > > &	almT,
		Alm< xcomplex< T > > &	almG,
		Alm< xcomplex< T > > &	almC,
		planck_rng &	rng
	)			`[inline]`

Creates a Gaussian realisation of the polarised input power spectrum powspec, using the random number generator rng, and returns the result in almT, almG and almC.

Definition at line 69 of file alm_powspec_tools.cc.

template<typename T>

void extract_powspec	(	const Alm< xcomplex< T > > &	alm,
		PowSpec &	powspec
	)			`[inline]`

Returns the unpolarised power spectrum of alm in powspec.

Definition at line 147 of file alm_powspec_tools.cc.

template<typename T>

void extract_crosspowspec	(	const Alm< xcomplex< T > > &	alm1,
		const Alm< xcomplex< T > > &	alm2,
		PowSpec &	powspec
	)			`[inline]`

Returns the cross power spectrum of alm1 and alm2 in powspec.

Definition at line 168 of file alm_powspec_tools.cc.

template<typename T>

void extract_powspec	(	const Alm< xcomplex< T > > &	almT,
		const Alm< xcomplex< T > > &	almG,
		const Alm< xcomplex< T > > &	almC,
		PowSpec &	powspec
	)			`[inline]`

Returns the polarised power spectrum of almT, almG and almC in powspec.
