Modelling the radio-FIR SED of IFRS xFLS 478. The total SED (solid line) is composed of the SED of a star forming galaxy (dashed line) from Murphy (2009) and the radio SED of 00183 (dotted line) from Norris et al. (2012). The star forming SED template is again composed of synchrotron, free-free, and thermal dust components. The best model was found at z = 1.1 and is shown in this figure. Black dots represent the photometric data points of xFLS 478 with respective 1σ uncertainties.
