Overview of the helium doppler maps in the sunspot. The left helium Doppler map displays velocities inverted using a one-component atmosphere. The green contours show sunspot intensity boundaries. The purple contour shows areas with high Doppler shifts. The right images show results from inversions with two chromospheric models and one photospheric model. The green line shows the boundary between the penumbra, and the quiet Sun.
