Demigrog asks:

I am not clear on where all the measurements took place (some in space some on earth). In either case, when taking the measurements / launching the vehicles, one makes an assuption that the earth is translating and rotating.One then makes an assumption about the final configuration relative to a "fixed" star system. The dipole isotropy is removed by transforming out these assumptions. According to the Einstein's equivalence principle (the basis of the Born quote in the initial message), all reference frames are valid, so if one assumed what I said, it equally could be the case that the earth is staionary and the universe is spinning. Presumably in this case this would include the CMB rotating. In fact the experiments were likely all done on a geostationary basis anyway!
