Spatial distribution of the velocity along the LOS inferred from the Doppler shift of the Si I 10827 Å (left), Ca II 8542 Å (middle), and He I 10830 Å (right) spectral line centres. The contours tentatively define the area corresponding to the umbra and penumbra computed from the continuum intensity maps presented in Figure 2.
