There // is one peak half at 0 and half at about 450. // That's because the parametrization of // the contour started at the highest peak and // terminated there. Note also that the shape had to // be considerably smoothed so the curvature doesn't // blow up at the very sharp peaks of the star. // chdir(initial_dir); |  |  |
