GRB host galaxy optical through to submm spectral energy distributions for our sample of five GRBHs observed with Herschel. Detections are plotted as filled symbols, and open circles represent 3σ upper limits. The lePHARE best-fit template galaxy models fitted to the optical to mid-IR data are shown (dashed black line), as well as our modified blackbody fits to the FIR and submm data (red solid line) (see Table 4 for details). In those cases where the host galaxy is not detected with Herschel, the modified blackbody fits are used to determine the upper limit on the corresponding dust mass and SFR.
