The solid lines indicate intrinsic values of ∆100 approximately projected for varying inclinations with ∆int = 100, 250 and 400 km s −1 . The different kinematic classes and dust morphologies (see Chapter 3) are indicated. Filled symbols represent rotators: with dust disks (•), with dust lanes (�) or with irregular dust (�); Empty symbols represent non-rotators: with dust disks (◦), with dust lanes (�) or with no-dust or irregular dust (△). 258
