The corresponding series of 1025 fractional frequency deviates (middle plot of Figure 318)
can be computed by taking the first differences of the time differences
and dividing by 8.64
(for details, see Equation (321c) and the discussion following it).
The first 1024 of these deviates are also shown
in the bottom plot of Figure 8.
