Directional analysis of the GRBs fluence: masked case. Left panel: distribution of GRB on the celestial sphere of the FERMIGRB masked sample, showing 2428 GRBs, where we implemented a cut of the zone of avoidance removing GRBs with |b|≤20° (in Galactic coordinates). Middle and Right panels: $f^{{\mathrm{FERMI}}_{\mathrm{MKD}}}$-map with resolution N_side = 4 (middle panel) and its dipole component (right panel) for the FERMIGRB-Masked sample. All the maps are in units of erg/cm² and in the Galactic coordinate system.
