SEDs of the young brown dwarfs detected with Herschel. All fluxes have been dereddened using the visual extinction values from Table 1 and are shown as filled circles for >3σ detections; open squares depict marginal detections (1<σ<3), and open triangles show 1σ upper limits. The original fluxes are marked with open circles. The Herschel/PACS wavelength range is shown by the red shaded region, and for GY92 344 the Herschel/SPIRE wavelength range is marked by the green shaded region. NextGen model photospheres are shown in light grey. The model with the best-fit parameters is overplotted in blue.
