)

Description [src]

Logarithmic counterpart of nc_galaxy_shape_factor_eval_marginal().

Parameters

pop

Type: NcGalaxyShapePop

The NcGalaxyShapePop intrinsic-ellipticity model.

The data is owned by the caller of the method.
data

Type: NcGalaxyShapeFactorData

A NcGalaxyShapeFactorData.

The data is owned by the caller of the method.
g_1

Type: const gdouble

Real part of the reduced shear (bias applied).

g_2

Type: const gdouble

Imaginary part of the reduced shear (bias applied).

epsilon_obs_1

Type: const gdouble

Observed ellipticity component 1 (same frame as g_1, g_2).

epsilon_obs_2

Type: const gdouble

Observed ellipticity component 2 (same frame as g_1, g_2).

Return value

Type: gdouble

The natural logarithm of the marginal probability density.
