Notes. The afterglow magnitudes forming the SEDs are corrected for the Galactic reddening, E(B − V),Gal, along the line of sight. In the case of GRB 120714B the afterglow SED was only roughly determined based on VLT/X-shooter data taken 0.353 days after the burst (see Sect. 3.3). In this case, for the SN light curve fits 
mag is assumed, not measured. In order to be consistent with the host-galaxy measurements (see Table C.4), in the case of GRB 130831A afterglow coordinates were measured on the VLT acquisition images. Otherwise GROND images were used.
