Δθ_std	Standard deviation of the jet opening angle	4°
log r_0,mean	Mean log GRB radius	13 log cm
log r_0,std	Standard deviation of log GRB radius	0.1 log cm
log E_GRB,mean	Mean of total GRB energy	49.3 log ergs
log E_GRB,std	Standard deviation of total GRB energy	0.5 log ergs
	the mean value of the reference frequency in the jet co-moving frame	0.001 MeV
	Standard deviation of the reference frequency in the jet co-moving frame	0.00075 MeV
γ_mean	Mean of the bulk Lorentz factor	250
γ_std	Standard deviation of the bulk Lorentz factor	75
t_d,std	Standard deviation of the time delay t_d	0.4 s

Notes. Their default values are listed in the third column, with which the historical observation can be optimally reconstructed.
