Figure 1: The observed continuum of Ark 564 compared to the results of the multi-cloud model M1. The observed data from the NED are shown as filled squares. Open squares refer to the data of Walter & Fink (1993) in the X-ray and of Rodríguez-Pascual et al. (1997) in the UV. The multi-cloud emission, corresponding to dust emission and bremsstrahlung (thick solid lines) obtained from the weighted average of the clouds (thin solid lines) are shown, as well as the synchrotron emission from the shock front (dashed line). The old stellar population is represented by a blackbody (dot-dashed line). The frequency range where intrinsic absorption reduces the continuum flux is limited by the two thin vertical lines (see text).
