Detailed Description

Computes the evolution gauge Bondi \(\hat R\) on the worldtube from Cauchy gauge quantities.

Details

The evolution gauge Bondi \(\hat R\) obeys:

\begin{align*} \hat R = \hat \omega R(\hat x^{\hat A}), \end{align*}

where the evaluation of \(R\) at \(\hat x^{\hat A}\) requires an interpolation to the evolution coordinates, and \(\hat \omega\) is the conformal factor associated with the angular part of the gauge transformation.
