Spacetime derivatives of the gauge source function for the generalized harmonic system.
In the generalized / damped harmonic gauge, the right hand side of the gauge equation \( \square x_a = H_a\) is sourced by non-vanishing functions \( H_a\). This variable stores their spacetime derivatives \( \partial_b H_a\).
