    "abstract": "The anisotropy of the speed of light at 1 part in 10^3 has been detected by\nMichelson and Morley (1887), Miller (1925/26), Illingworth (1927), Joos (1930),\nJaseja et al. (1964), Torr and Kolen (1984), De Witte (1991) and Cahill (2006)\nusing a variety of experimental techniques, from gas-mode Michelson\ninterferometers (with the relativistic theory for these only determined in\n2002) to one-way RF coaxial cable propagation timing. All agree on the speed,\nright ascension and declination of the anisotropy velocity. The Stephan Marinov\nexperiment (1984) detected a light speed anisotropy using a mechanical coupled\nshutters technique which has holes in co-rotating disks, essentially a one-way\nversion of the Fizeau mechanical round-trip speed-of-light experiment. The\nMarinov data is re-analysed herein because the velocity vector he determined is\nin a very different direction to that from the above experiments. No\nexplanation for this difference has been uncovered.",
