Detailed Description

Computes the evolution gauge quantity \(\hat \Pi\) for the scalar field on the worldtube.

The evolution gauge \(\hat \Pi\) obeys

\begin{align*} \hat \Pi = \partial_{t^\prime} \psi + \Re \left(\mathcal{U}^{(0)}\bar{\eth}\psi\right) \end{align*}

where \(\partial_{t^\prime} \psi\) comes from the Cauchy evolution.
