Left panel: expected vs. M_BH relations for AGN with an accretion rate of 0.01 (red lines) and 1 (blue lines) in Model B scenario and computed with 250 s bins and 80 ks intervals. Middle left: same as before but for 40 ks intervals. Middle right: same as before but for 20 ks intervals. Dashed lines show the expected computed with time bins of 50 s. Right panel: 10 ks intervals.
