GRB classification diagram in the E_p−T₉₀ domain. The crosses and circles represent the known classification of SGRB-Is and GRB-IIs in the MP sample. The different colors indicate the probability of a GRB event being a SGRB-I (P_SGRB−I) based on two independent two-dimensional Gaussian components. The dashed cyan line indicates the dividing line with P_SGRB−I = 0.5. In the top and right projected histograms, the blue and red lines represent the contributions from SGRB-I candidates (smaller T₉₀, larger E_p) and GRB-II candidates (larger T₉₀, smaller E_p), while the black lines are the combined distributions of two Gaussian components.
