Regular Evershed flow and strong red-shifts in penumbrae from Hinode/SP observations. Top panels – continuum intensity at 630 nm. Bottom panels – bisector velocity derived at the 70% intensity level of the 6301.5 Å line. Panel numbers are indicated on the top left corner while the number of scan steps for each panel is shown at the bottom left. The start of the scanning sequence coincides with panel 8 of Fig. 2. The green triangle and square are centered on pixels whose Stokes profiles are shown in Fig. 4.
