Response: The case of absence of transverse Doppler effect

Measurements that were done have yielded a gamma factor due to the quantum-mechanical absorption of photons in the detectors, thereby transferring the mass of photons into the detectors. It is said that if reflectors were used instead of detectors, then no gamma factor would have been obtained. Hence, it has not been demonstrated in the comment that the equations of the relativistic Doppler effect had been misapplied. In fact, it seems that those equations may have been improperly applied in the comment.
