ABSTRACT:In the present wavelet analysis of the C-13O spectral data from L1551's outflow region, the fractal Hausdorff dimension of the data space consisting
of the centroid velocities over the x-y plane is noted to be definable as 2.35 + or - 0.01.
An analysis of surface density yields a dimensional value
close to 3, rather than Prasad and Sreenivasan's (1990) 2.36 + or - 0.05 for the
Kolmogorov range of the turbulence associated with a water jet in quiet
surroundings; this suggests that there is gas between the emissivity peaks, as
supported by the larger dominant structure found for the surface density.
