Figure 3: Radio spectra of the central object and of the extended nebula. For the compact object, triangles indicate the measurements used in the fit to derive the spectral index. Diamonds indicate extrapolations of such a fit to the lower frequencies. For the extended nebula, the optically thick spectrum (dotted line) and optically thin spectrum (dashed line) of a free-free emitting radio sources are shown for comparison. |
