Example of a feature that appears on a granular edge in the emergence run at t = 156 s. Resulting Stokes I, Q, U and V profiles at the pixel shown in Fig. 7. Upper panels: synthesised IMaX observations at the original resolution (black line) and for the diffraction-limited resolution, stray-light and noise are taken into account (red line); lower panels: synthesised Hinode observations, the Fe I 630.25 nm at the original spatial resolution (black), at the spatial resolution of Hinode (blue), and with the spectral resolution of IMaX (red).
