The CCZ4 temporary expression \(\tau^{1} \tilde{\gamma}_{ij}\).
Here, \(\tilde{\gamma}_{ij}\) is the conformal spatial metric defined by Ccz4::Tags::ConformalMetric
and \(\tau\) is the relaxation time to enforce the algebraic constraints on the determinant of the conformal spatial metric and on the trace of the tracefree part of the extrinsic curvature that is defined by Ccz4::Tags::ATilde
