Fig. 4.


Spicules seen in near-limb images at 3 mm ( top panels) and Hα (bottom panels). All images have been rotated to make the limb parallel to the horizontal direction and corrected to reduce the sharp drop of intensity near the limb by subtracting 90% of the azimuthally averaged intensity. The black curve marks the photospheric limb and the inserts show the ALMA beam.
