Notes. GRB: GRB name. Host: the chosen extinction law; Milky Way (MW), Large Magellanic Cloud (LMC), Small Magellanic Cloud (SMC). Part: X-ray LC part considered; S steep decay, P plateau, N normal decay. βop,X, σ(βop,X): spectral index with error. NH, σ(NH): hydrogen column density with relative error (1022 cm-2). E(B − V), σ(E(B − V)): optical absorption with relative error (mag). N, σ(N): normalization with error (mJy). χ2: chi-square. d.o.f.: degree of freedom. pval: p_value. Ti, Tf: initial (end) time of the interval of the SED in observer time (s). Ok: 1 if the best fitting function is a power-law, otherwise 0. This table is available in its entirety in a machine-readable form at the CDS (table2c.dat, ReadMe). A portion is shown here for guidance.
