(optics)
An experiment which uses a Michelson interferometer to determine the difference between the speeds of light in two perpendicular directions.

What Robertson did not say explicitly was that PULC is also a consequence of the Michelson-Morley experiment (given the standard Einstein convention for synchronizing clocks, which Robertson explicitly adopted), despite the fact that variations in the speed of the light-source was not a feature of the experiment.
(iii) We have seen, then, that given Einstein's light postulate PLC, the principle PULC can be justified by appeal either to the weak principle of relativity or to the Michelson-Morley experiment. Now in their 1984 work referred to above, Tzanakis and Kyritsis raised the question whether the Lorentz transformations follow from PULC, weak-PR and Einstein's remaining postulates.
Light speed anisotropy has been repeatedly detected over more than 120 years, beginning with the Michelson-Morley experiment in 1887 [1].
Tangherlini's formula (2) gives an explanation to the results obtained in the Michelson-Morley experiment [9] and also in the Kennedy-Thorndike experiment [10], because, according to Tangherlini's formula, the common time of the travel of a light beam toward and backward doesn't depend on the velocity v the inertial reference frame K' moves with respect to the "preferred" inertial reference frame K.

With this transformation in hand, the constancy of the speed of light can be deduced and the Michelson-Morley experiments [7] satisfied.
Another important development is the re-interpretation of the Michelson-Morley experiments [10, 11] which show that they had not been evaluated in the right way.
The new interpretation of Michelson-Morley experiments is compatible with this concept.
