GRB 170817A in the Ep − Eiso correlation diagram. The solid lines are the best-fit correlations: logEp/(1 + z) = (3.24 ± 0.07) + (0.54 ± 0.04)log(Eiso/1052) for short GRBs, logEp/(1 + z) = (2.22 ± 0.03) + (0.47 ± 0.03)log(Eiso/1052) for long GRBs. Red dashed line represents GRB 170817A position if it were in different redshifts ranging from 0.009 to 3. All error bars represent 1−σ uncertainties
