Notes. Predicted spectral slope βtheo for the afterglows adopting for the power-law index p of the electron distribution function a value p > 2 (GRB 071112C, 111228A, 120714B, 130831A) or p < 2 (GRB 111228A; Zhang & Mészáros 2004). Values for α1 and α2 are taken from Table C.2. Individual events: GRB 071112C: the observed decay slope α implies that the afterglow is in the spherical expansion phase. GRB 111228A: shown here are the results for the extended data set (which suggests p > 2) and for the GROND-only data (which imply p < 2). GRB 120714B: the observed decay slope α implies that the afterglow is in the spherical expansion phase. GRB 130831A: the observed decay slope could either be pre- or post-break. Therefore, both options are calculated.
