Function

NumCosmowl_ellipticity_shear_at_origin_trace_ptr

Declaration [src]

void
nc_wl_ellipticity_shear_at_origin_trace_ptr (
  const NcmComplex* target,
  NcmComplex* g
)

Description [src]

Computes the reduced shear g such that nc_wl_ellipticity_apply_shear_trace_ptr() maps a zero intrinsic distortion to target, in the trace (distortion) convention. Requires $|target|<1$.

Parameters

target

Type: NcmComplex

Point in the disc, as a NcmComplex.

The data is owned by the caller of the function.

g

Type: NcmComplex

Output reduced shear as a NcmComplex.

The data is owned by the caller of the function.
