Detailed Description

template<typename DataType, size_t Dim, typename Frame>
struct Xcts::Tags::LongitudinalShiftExcess< DataType, Dim, Frame >

The conformal longitudinal operator applied to the shift excess \((\bar{L}\beta_\mathrm{excess})^{ij}\).

This quantity can be used as the "flux" for the momentum constraint in formulations of the XCTS equations, because the principal part of the momentum constraint is essentially the divergence of this quantity.
