Directional analysis of the GRBs angular correlations: SGRB and LGRB cases. The first/second row corresponds to the SGRB/LGRB angular distribution analyses. Left panel:σ^SGRB/LGRB-map obtained from the directional analyses of the SGRB and LGRB samples. Middle panel: Corresponding dipole component of the σ^SGRB/LGRB-map. Right panel: Power spectrum ${\mathcal{S}}_{\ell }^{\mathrm{SGRB}/\mathrm{LGRB}}$, ℓ = 1, ..., 5 of the σ^SGRB/LGRB-map shown as dots, and the median power spectrum of 500 isotropic σ-maps are shown on the solid line. The shaded region corresponds to 1 σ and 2 σ deviations from the isotropic case.
