The linemaps of [Fe ii] and [Si vi] are shown in panels a) and b), and the single pixel spectra and fits to these lines are shown in panels c) and d). A linear continuum contribution was assumed. The flux density is given in units of 10^-16   W   m^-2   μm^-1. The black contours in b) represent a VLA observation from Thean et al. (2000) at 8.4 GHz. The beam size is shown in the lower left corner (filled grey).
