2.The connecting field comes from the infinitesimally brief moment when the motion transitions from uniform velocity to hyperbolic. In J. J. Thomson's classic model of a charge that starts or stops ( E. M. Purcell and D. J. Morin, Electricity and Magnetism, 3rd ed. ( Cambridge U.P., Cambridge, 2013), Sect. 5.7), the velocity is discontinuous, so the acceleration is a delta function. In our case, the acceleration is discontinuous, and the delta function is in the jerk. But the Liénard–Weichert field [Eq. (2)] does not explicitly involve the jerk, and it does not pick up a delta function. We thank D. Cross for this observation.

4.Cross has also shown how one can obtain the “extra” delta-function term directly from the Liénard–Weichert construction, without truncating the hyperbolic motion. See D. J. Cross, “ Completing the Liénard–Weichert potentials: The origin of the delta function for a charged particle in hyperbolic motion,” Am. J. Phys. (accepted); e-print arXiv:1409.1569.
