Consider a dipole moment, **m** or **d**, which is
time-independent in its own accelerated frame. The augmented Larmor
formula, Eq.(70) and
(69), yields zero radiative
-momentum relative the expanding inertial frame in Rindler
sector :

Equations (73)-(76) express an observationally and hence conceptually precise distinction between the radiative and non-radiative e.m. fields of a dipole source accelerated in Rindler sector : The augmented Larmor formula implies that the dipole emits radiation if and only if its -momentum, the spatial integral of in the expanding inertial frame, is non-zero. Furthermore, the existence of a dipole field, static in Rindler sector , is expressed by the non-vanishing of the other momenergy components, Eqs.(74)-(75). Like the -momentum, these components are also measurable in the expanding inertial frame. If the dipole is not static then the the emitted radiation gets tracked by the -momentum. In that case the other momenergy components play an auxiliary role. They only track the sum of static dipole field and the radiative field, not the separate contributions.
