Description [src]

Computes the natural logarithm of the absolute value of the Jacobian determinant of the transformation from intrinsic to observed ellipticity.

Parameters

g

Type: NcmComplex

Input reduced shear as a NcmComplex.

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

Type: NcmComplex

Input observed ellipticity as a NcmComplex.

The data is owned by the caller of the method.

Return value

Type: gdouble

The log-determinant of the shear Jacobian.
