Function

NumCosmowl_ellipticity_lndet_jac_trace_det_ptr

Declaration [src]

gdouble
nc_wl_ellipticity_lndet_jac_trace_det_ptr (
  const NcmComplex* g,
  const NcmComplex* e_obs
)

Description [src]

Computes the natural logarithm of the absolute value of the Jacobian determinant of the intrinsic -> observed map at e_obs, in the trace-determinant (ellipticity) convention.

Parameters

g

Type: NcmComplex

Reduced shear as a NcmComplex.

The data is owned by the caller of the function.

e_obs

Type: NcmComplex

Observed ellipticity as a NcmComplex.

The data is owned by the caller of the function.

Return value

Type: gdouble

The log-determinant of the shear Jacobian.
