\subsubsection{Spatial Power Spectrum}  To obtain the Spatial Power Spectrum, spatial power spectrum,  we compute the Fourier Transform of our two integrated intensity maps, maps  and calculate the 2-Dimensional 2D  power spectra (of of  the two-point autocorrelation functions). functions.  We then radially average our these  power spectra over the bins in  spatial frequencies. frequency.  Fitted power laws for each 1-D Power Spectrum 1D power spectrum  are shown in Figure 7. We find similar results to that of the VCA: a constant horizontal offset, offset with the winds exhibiting more power overall  and a minor difference in slope.
