Calculate \(\Psi_0\) and its radial derivative \(\partial_\underline{\lambda}\Psi_0\) at the inner boundary of the CCE grid.
This action is to be called after Tags::BondiJ
has been updated. Note that Tags::BondiJ
is in the asymptotically inertial frame, while the returned \(\Psi_0\) and its radial derivative are in the Cauchy frame. \(\underline \lambda\) is an affine parameter along the null rays generated by \(l\), see Eq. (19a) of [134].
