Checks the interpolation managers and if they are ready, performs the interpolation and sends the data to file.
This uses the ScriPlusInterpolationManager to perform the interpolations of all requested scri quantities (determined by scri_values_to_observe in the metavariables), and write them to disk using observers::threadedActions::WriteSimpleData. When using an analytic worldtube solution, this action also uses the AnalyticBoundaryDataManager to output the expected News value at the appropriate asymptotically inertial time.
Tags::EthInertialRetardedTime, interpolated to the inertial frame, to perform the coordinate transformations presented in [27] to the Weyl scalars after interpolation. For our formulas, we need to adjust the signs and factors of two to be compatible with our definitions of \(\eth\) and choice of Newman-Penrose tetrad.\begin{align*} \Psi_0^{\prime (5)} =& \Psi_0^{(5)} + 2 \eth u^\prime \Psi_1^{(4)} + \frac{3}{4} \left(\eth u^\prime\right)^2 \Psi_2^{(3)} + \frac{1}{2} \left( \eth u^\prime\right)^3 \Psi_3^{(2)} + \frac{1}{16} \left(\eth u^\prime\right)^4 \Psi_4^{(1)}, \\ \Psi_1^{\prime (4)} =& \Psi_1^{(4)} + \frac{3}{2} \eth u^\prime \Psi_2^{(3)} + \frac{3}{4} \left(\eth u^\prime\right)^2 \Psi_3^{(2)} + \frac{1}{8} \left(\eth u^\prime\right)^3 \Psi_4^{(1)}, \\ \Psi_2^{\prime (3)} =& \Psi_2^{(3)} + \eth u^\prime \Psi_3^{(2)} + \frac{1}{4} \left(\eth u^\prime\right)^2 \Psi_4^{(1)}, \\ \Psi_3^{\prime (2)} =& \Psi_3^{(2)} + \frac{1}{2} \eth u^{\prime} \Psi_4^{ (1)}, \\ \Psi_4^{\prime (1)} =& \Psi_4^{(1)}. \end{align*}
WriteSynchronously is true, then a local synchronous action will be used to write the News value rather than a threaded action.DataBox changes:
