You are incorrect. Quoting more of the text, "The observed, two-way anomalous effect *can be expressed* to first order in v/c as ...." (emph added.) That the anomaly *can be expressed* in that fashion for reader edification does not mean it was "actually used" that way in the analysis. In fact, the *actual* Doppler analysis as described by Moyer (Anderson's footnote 42) uses the fully relativistic formulation. The Anderson authors display their equation 15 to first order in v/c because it is more instructive that way. The fully relativistic expression is far more complicated and the anomalous contribution would be difficult to discern. CM
