5. Actually, some weak excitations called "forerunners" may arrive even before the main front, but not faster than c. Their speed has been called, somehow unfortunately, "front velocity".

18. It can be easily shown from (2) that this preselection maximizes the mean time of arrival t.
19. We were not able to correctly fit the shape of these curves. This is probably due to a saturation of the OTDR detection or to some phase noise that invalidates the first step of the fitting procedure.
