AGN STORM meeting - Susanna Bisogni � EW[OIII]: summary � Both Broad and Narrow Lines behaviours confirm EW[OIII] is a good orientation indicator: � � - BLR is disk-shaped � - outflows in the NLR � Analysis of the IR SED confirms the torus is co-axial with the disk and the BLR and probably clumpy � Perspectives � Better understanding of geometry and kinematics of the inner components � Correcting virial mass estimates � Looking for Changing Look Quasars as a function of EW[OIII] �
