Rows, top to bottom: first row: Hinode SP continuum images with the 2D field of the apparent horizontal velocities calculated by the local correlation tracking (LCT) method shown with colored arrows. Black contours denote at ± 30 Mx cm^-2 and the times above the panels refer to the IRIS time line. In the second row the continuum images are now overplotted by contours of the absolute of magnetic flux density from absolute 20 Mx cm^-2 to 60 Mx cm^-2 in steps of 10 Mx cm^-2. The last row shows the same continuum images now with filled contours of the magnetic field strength obtained from MERLIN inversions obtained with the default inversion parameters from http://www2.hao.ucar.edu/csac.
