Detailed Description

Computes the leading part of the scalar field \(\psi\) near \(\mathcal I^+\).

Details

The value \(\psi\) scales asymptotically as \(r^{-1}\). Assuming \(\psi^{(n)}\) is the \(1/r^n\) part of \(\psi\) evaluated at \(\mathcal I^+\), so for any \(\psi\),

\begin{align*} \psi^{(1)} = (- 2 R \partial_y \psi)|_{y = 1}, \end{align*}

where the expansion is determined by the conversion between Bondi and numerical radii \(r = 2 R / (1 - y)\).
