Host-subtracted SED of the optical transient following GRB 120714B at t = 0.353 days (observer frame), consisting of GROND (black) and binned X-shooter (gray) data (step size 60 nm). The thick black line shows the best fit for a two-component model (indicated by the red broken lines) consisting of afterglow light with a spectral slope of β = 0.7 and a black body with a temperature of eV. Wavelengths and frequencies are given in the host-galaxy frame.
