Table 2:
Times for the different phases in the evolution of the
perturbed jet models. In Cols. 2-4 we show:
- end of
linear phase (the ratios of amplitudes of the different quantities are
not constant any longer),
- end of saturation phase (the
amplitude of the transverse speed perturbation reaches its maximum),
- the peak in the amplitude of the pressure
perturbation is reached. (see Fig. 2). Note that,
as a general trend,
.
In Col. 5 we show the saturation time in dynamical time units and
in the jet reference frame.
