We use an iteration method in two different approaches, single and two-component modified black body models. In both approaches, $\\beta$ is higher in the central disk than in the outer disk similar to the dust temperature. There is a positive correlation between $\\beta$ and Halpha as well as with the molecular gas traced by CO(2-1). A Monte-Carlo simulation shows that the physical parameters are better constrained when ","authors_text":"C. Henkel, C. Kramer, D. Calzetti, E. Schinnerer, F. Combes, F. Israel, F. S. Tabatabaei, J.
