Power spectra of the column density (blue) and the velocity (purple) for the VCF crests 1 (left), 32 (middle), and 47 (right). The amplitudes of the power spectra are scaled so they can be plotted on the same panel. The red lines show the best linear fit to the power spectra and the values of the slopes are indicated in the corresponding panels. The vertical black solid lines indicate the 30.″2 angular resolution of the data equivalent to ~1.2 arcmin^-1, which is the highest frequency data point used to fit the power spectra.
