Figure 3: Left panel: electron density map (cm-3) derived using the line ratios Fe XII 186 and 195 Å. Middle panel: electron density map overplotted with magnetic field contours. Red contours correspond to positive polarity region whereas blue contours represent negative polarity regions. Right panel: MDI magnetogram of the corresponding region. |
