Zoomed-in views of the distribution of the QSL maps at z = 0.4 Mm (gray color scale, left) and of the photospheric (line-of-sight component) magnetic field (gray color scale, middle, right), as well as selected magnetic field lines for April 15 (top) and April 16 (bottom). For better visibility field lines in panels (c), f)) are vertically stretched by a factor of 2. The color scale for the magnetic field is saturated at ±300 Gauss and black/white indicates a negative/positive magnetic field.
