Halfspheres

The resulting surface velocity field is then analyzed in various settings: Two 360#92;circ#92;times 90#92;circ halfspheres, two 120#92;circ#92;times 60#92;circ patches on the front and farside of the Sun (North and South, respectively) and two 120#92;circ#92;times 60#92;circ patches on the northern and southern frontside only.
