Continuum map of AR10926 composed from the fitted Stokes I profiles (left) and LOS velocity map at log τ = 0.0 (right). Positive values (red/yellow colors) denote downflows. The direction toward the disk center (DC) is indicated by the black arrow. The boxes (B1), (B2), and (B3), and the lines (C1) (in the center), (C2) (top left), and (C3) (top center) correspond to regions analyzed in Sect. 4. The red, cyan, and yellow crosses in the continuum image mark the granules used to determine the average atmospheric parameters in Table 1 for LBGs, PlGs, and QSGs, respectively.
