Detailed Description

Calculate ${\mathrm{\Psi }}_0$ and its radial derivative ${\partial }_{\underset{\_}{\lambda }}{\mathrm{\Psi }}_0$ at the inner boundary of the CCE grid.

Details

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 ${\mathrm{\Psi }}_0$ and its radial derivative are in the Cauchy frame. $\underset{\_}{\lambda }$ is an affine parameter along the null rays generated by $l$, see Eq. (19a) of [145].
