<< At the location of the correlator the data is played
back. The timing of the playback is adjusted according
to the atomic clock signals on the
(tapes/disk drives/fibre optic signal), and the
estimated times of arrival of the radio signal at each
of the telescopes. A range of playback timings over a
range of nanoseconds are usually tested until the
correct timing is found. >>
