Demonstration of Magnetic Charge Topology analysis, characterizing the coronal magnetic topology of NOAA AR 11283 (Fig. 3), 2011.09.07 at 21:48:00 TAI. Top: magnetogram showing the vertical field (greyscale), the partitions (contours), and the locations of the sources (+ and × for positive and negative). Areas outside of the active-pixel bitmap (cf. Fig. 3) are set to zero. Bottom: same as top panel, but schematically showing the connectivity matrix (blue lines) with dark/thick lines indicating more flux in the connection than light/thin lines.
