Active region NOAA 11072. The upper row shows information contained in the SHARPS CEA data, namely (a) the maps of the continuum intensity, provided here for context, (b) the vertical component, B_z, and (c and d) the horizontal B_x and B_y components of the photospheric magnetic field. The magnetic field values were scaled to ±500 G for the vertical component and ±400 G for the horizontal ones. The lower row contains (e) the measure of the horizontal field B_hor, (f) the azimuth ranging from −180° to 180°, (g) the inclination ranging between −90° and 90°, and (h) the COCOMAG produced by B_x, B_y, and B_z. Contours of the continuum intensity were added to mark the boundaries of the umbra and the penumbra of the spot for context.
