In panels a and b we show observations from 2006-12-27 13:20 and 2007-01-07 19:20, respectively. STEREO/EUVI observations of the 304 Å channel are given for comparison and scaled by their maximum and minimum value. The magnetograms show the absolute values of the LOS magnetic field strength and are scaled linearly to 2000 Gauss. The flux distribution at the full-disk scale is in agreement between the ITI and SOHO/MDI observations. The comparison of the active region in a shows that the ITI magnetogram matches the overall flux distribution. The active region in b shows larger deviations that mainly originate from confined regions (i.e., sunspots) where ITI overestimates the magnetic field strength.
