Detailed Description

Projects the regular field ${\mathrm{\Psi }}^R$ and its time derivative ${\partial }_t{\mathrm{\Psi }}^R$ onto real spherical harmonics and sends the result to the worldtube.

Details

The regular field is obtained by subtracting the singular/puncture field from the numerical DG field. All spherical harmonics are computed for $l<=n$, where $n$ is the worldtube expansion order. The projection is done by integrating over the DG grid of the element face using definite_integral with the euclidean area element. The worldtube adds up all integrals from the different elements to obtain the integral over the entire sphere.
