The upper panel shows the smoothed excess emission map on the time-energy plane for the Fe K? as measured for NGC 3516. The resolution is 100eV in energy and 2 ks in time. The colour coding is according to a �blackblody� with the brightest pixels correspond to about 15 excess counts. The spectral evolution agrees with emission arising from a spot on the accretion disc, illuminated by a corotating flare located at a radius of 3.5 - 8 Rs (Schwarzschild radii). The lower panels shows a theoretical picture for comparison.
