Spectra of isotropic wavelet coefficients (top panel), angular spectrum of anisotropic wavelet coefficients (central panel), and local and global degrees of anisotropy (bottom panel) for the Polaris column-density map computed for filter parameters of and . In the 2D map of wavelet coefficients, the results from the filter are given in colors while those from the filter are given in contours. Angles are plotted in radians. The dashed lines mark the spatial resolution of the map of 36 arcsec limited by the 500 μm observations.
