Class
NumCosmoGalaxySDShapeGauss
Description [src]
final class NumCosmo.GalaxySDShapeGauss : NumCosmo.GalaxySDShape
{
/* No available fields */
}Class describing a galaxy sample shape distribution with a truncated gaussian p.d.f. convoluted with gaussian noise.
Functions
nc_galaxy_sd_shape_gauss_clear
Decrease the reference count of gsdsgauss by one, and sets the pointer *gsdsgauss to
NULL.
nc_galaxy_sd_shape_gauss_sigma_from_std_shape
Computes the internal variance parameter ($\sigma$) of the Gaussian shape model corresponding to a given observed shape dispersion ($s$).
nc_galaxy_sd_shape_gauss_std_shape_from_sigma
Computes the physical (true) shape standard deviation $s$ corresponding to a given internal Gaussian model dispersion $\sigma$.
Instance methods
nc_galaxy_sd_shape_gauss_data_get
Gets the observed ellipticity components and the gaussian noise dispersion.
nc_galaxy_sd_shape_gauss_data_set
Sets the observed ellipticity components and the gaussian noise dispersion.
Methods inherited from NcGalaxySDShape (10)
nc_galaxy_sd_shape_apply_shear
Applies the reduced shear g to the intrinsic ellipticity E, storing the resulting
observed ellipticity in E_obs. The transformation depends on the
NcGalaxySDShapeEllipsisType configured in gsds.
nc_galaxy_sd_shape_apply_shear_inv
Applies the inverse shear transformation using g to recover the intrinsic
ellipticity E from the observed ellipticity E_obs. The transformation depends
on the NcGalaxySDShapeEllipsisType configured in gsds.
nc_galaxy_sd_shape_direct_estimate
Computes the estimate of the galaxy shape using the direct method.
nc_galaxy_sd_shape_free
Decreases the reference count of gsds by one.
nc_galaxy_sd_shape_gen
Generates a new galaxy shape. The NcGalaxySDShapeData object data must be
initialized before calling this method.
nc_galaxy_sd_shape_get_ellip_conv
Gets the ellipse type of gsds.
nc_galaxy_sd_shape_integ
Creates a new galaxy shape integrand.
nc_galaxy_sd_shape_lndet_jac
Computes the natural logarithm of the absolute value of the Jacobian determinant of the transformation from intrinsic to observed ellipticity.
nc_galaxy_sd_shape_prepare_data_array
Prepares the matrix to compute the probability density of the observable shape.
nc_galaxy_sd_shape_ref
Increases the reference count of gsds by one.
