Thanks for the comments. But rather than resolving the issue, they seem to me rather to underscore the problem, which is the two different formulas for time retardation which Einstein presents in his 1905 paper. The first, the Lorentz transformation, is that which is widely used and and...

I recently decided for some reason to re-read some of the first part, the kinematical part, of Einstein’s initial paper on relativity, “The Electrodynamics of Moving Bodies”, in which he develops the conceptual framework of special relativity and derives the Lorentz transformations. I must have...
