NRSurRemnant_LoadH5File()

void NRSurRemnant_LoadH5File	(	LALH5File **	file,
		const char *	NRSurRemnant_DATAFILE
	)

Loads H5 file for a NRSurRemnant model.

Parameters

file	Output: Returns the opened H5 file.
NRSurRemnant_DATAFILE	H5 file name to load.

Definition at line 65 of file LALSimNRSurRemnantUtils.c.

NRSurRemnant_LoadScalarFit()

int NRSurRemnant_LoadScalarFit	(	ScalarFitData **	fit_data,
		LALH5File *	file,
		const char *	grp_name
	)

Loads a single NRSurRemnant GPR fit, as described in the supplementary materials of arxiv:1809.09125.

Parameters

fit_data	Output: Fit data. *fit_data should be NULL. Space will be allocated.
file	Opened H5 file.
grp_name	H5 group name.

Definition at line 97 of file LALSimNRSurRemnantUtils.c.

NRSurRemnant_LoadVectorFit()

int NRSurRemnant_LoadVectorFit	(	VectorFitData **	vector_data,
		UINT4	vec_dim,
		LALH5File *	file,
		const char *	grp_name
	)

Loads a vector of NRSurRemnant GPR fits.

Parameters

vector_data	Output: Vector of fit data. *vector_data should be NULL. Space will be allocated.
vec_dim	Length of the vector
file	Opened H5 file.
grp_name	H5 group name.

Definition at line 198 of file LALSimNRSurRemnantUtils.c.

PrecessingNRSurRemnant_Init()

int PrecessingNRSurRemnant_Init	(	PrecessingRemnantFitData *	sur_data,
		LALH5File *	file
	)

Initializes fit data for a precessing NRSurRemnant.

The data includes a ScalarFitData for the final mass, and a VectorFitData for the final spin and kick 3-vectors.

Parameters

sur_data	Output: Loaded surrogate data.
file	Opened H5 file.

Definition at line 239 of file LALSimNRSurRemnantUtils.c.

AlignedSpinNRSurRemnant_Init()

int AlignedSpinNRSurRemnant_Init	(	AlignedSpinRemnantFitData *	sur_data,
		LALH5File *	file
	)

Initializes fit data for an aligned-spin NRSurRemnant.

The data includes a ScalarFitData for the final mass, z-component of the final spin, and x and y components of the recoil kick. The other components of the spin and kick are zero due to the symmetries of aligned-spin systems and are not modelled by the surrogate.

Parameters

sur_data	Output: Loaded surrogate data.
file	Opened H5 file.
