Functions

nc_galaxy_sd_shape_clear

Decreases the reference count of gsds by one, and sets the pointer *gsds to NULL.

nc_galaxy_sd_shape_id
No description available.

Instance methods

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.
