Measured absolute (unfiltered) LOS velocities within the inter-spine (upper row) and spine masks (lower row) shown in Fig. 6, as obtained in the line core and with the COG method in the 5380 line and with the COG method in the 6301 line. The LOS velocities in the inter-spine mask show strong differences between the disk center and limb sides, demonstrating strong radial flows in the inter-spines, whereas no such differences are seen in the spines. Tick marks are at 1′′ intervals. The arrow points in the direction of Sun center.
