Table 1.
Prior distributions and bounds of model parameters used in the MCMC parameter estimation for the Gaussian-structured jet model.
| Parameter | Unit | Prior | Bounds |
|---|---|---|---|
| θobs | radians | uniform | [0,θC] |
| E0 | erg | log-uniform | [49, 54] |
| θC | radians | uniform | (0, π/6] |
| n0 | cm−3 | log-uniform | [–6,1] |
| p | – | uniform | (2, 3] |
| ϵe | – | log-uniform | [–4, log(1/3)) |
| ϵB | – | log-uniform | [–8, log(1/3)) |
| θW | radians | fixed | 2θC (Case I) |
| θW | radians | fixed | 1.5θC (Case II) |
Notes. For the uniform-jet model, the prior distributions and bounds are the same as in the Gaussian-structured jet model; only the truncation angle θW is missing as a model parameter in the case of a uniform jet. Square brackets indicate the bounds are included in the given interval, while round brackets indicate the bounds are excluded.
