SED of ESO 580-49, the host galaxy of GRB 111005A. Datapoints are shown as red squares and arrows, whereas GRASIL and MAGPHYS models are shown as a blue and black lines, respectively. The data at 100, 140 μm and in the radio were not used in the modelling due to either too poor spatial resolution, or resolving out the extended emission (see Sect. 3). The SED of the GRB 980425 host (Michałowski et al. 2014b) scaled up by a factor of four is shown for comparison (green line).
