Fig. 7.
Panel a: deprojected image of NGC 352 with parameters i = 71.6°, PA = 18.6°. Panel b: same image after applying an unsharp masking algorithm. In both panels we observe a barred-spiral morphology with a bar twisted close to its ends and tightly wound spirals. The red curves in panel b are parts of a logarithmic spiral of 5° pitch angle (see text).
