摘要：
We have obtained an Halpha position-velocity cube from Fabry-Perot interferometric observations of the HH 110 flow. We analyze the results in terms of anisotropic wavelet transforms, from which we derive the spatial distribution of the knots, as well as their characteristic sizes ( along and across the outflow axis). We then study the spatial behavior of the line width and the central radial velocity. The results are interpreted in terms of a simple "mean flow plus turbulent eddy ''jet/wake model. We find that most of the observed kinematics appears to be a direct result of the mean flow, on which are superposed low-amplitude (similar to35 km s(-1)) turbulent velocities.
