Reply to ''Comment on 'Ramsey spectroscopy, matter-wave interferometry, and the microwave-lensing frequency shift' ''

The Comment by Jefferts et al. [Phys. Rev. A 91, 067601 (2015)10.1103/PhysRevA.91.067601] discusses the microwave-lensing frequency shift's possible dependence on the initial wave-packet size and two effects of wall interactions, the frequency shifts that they produce, and the nature of how dressed states are clipped by apertures. I identify conceptual errors in their criticisms, some of which are related to fundamental problems in their lensing treatment [Ashby, Phys. Rev. A 91, 033624 (2015)10.1103/PhysRevA.91.033624] for the NIST-F1 and NIST-F2 atomic clocks [K. Gibble, arXiv:1505.00691]. Aside from typesetting errors that they note, the criticisms in the Comment are shown to be incorrect.
