Slice through penumbra is denoted by the black curved line in Fig. 3. Upper panel: normalized intensity along the slice. The solid line corresponds to uncorrected data and the dotted line to stray-light corrected data with (α = 0.6 and σ = 2″). Lower panel: same as upper panel but for velocity. It is seen that the dotted line shows significant patches of downflows (υ > 0).
