Figure 5.5 σ100 as a function of ∆100 for the sample nuclei (see text for def<strong>in</strong>itions).<br />

The solid l<strong>in</strong>e <strong>in</strong>dicates a 1:1 ratio of the two parameters. The different k<strong>in</strong>ematic<br />

classes <strong>and</strong> dust morphologies (see Chapter 3) are <strong>in</strong>dicated. Filled symbols represent<br />

rotators: with dust disks (•), with dust lanes (�) or with irregular dust (�); Empty<br />

symbols represent non-rotators: with dust disks (◦), with dust lanes (�) or with<br />

no-dust or irregular dust (△).<br />
