Fig. 4


Unscaled AGN model modified according to the variable torus obscuration interpretation. The outer layers of the torus (in gray) can be wiped out by an intense radiation field from the central region or when the torus is clumpy, by motion of individual clouds located on the observer’s line of sight. The spectral type of the AGN thus changes from type 1.9/2 to type 1.
