Detailed Description

Computes the Klein-Gordon source of the Bondi \(H\).

Details

Following the nomenclature of [156] and their Eq. (50), the scalar field contributes only to the regular part of the source term \(S_3^R\). The expression reads:

\begin{align*}2 \pi \frac{e^{2\beta}}{R}(\eth\psi)^2, \end{align*}

where \(\psi\) is the Klein-Gordon (scalar) field.
