| Aspect | Typical Treatment |
|--------|-------------------|
| Spectral Shape | Empirical Band function (broken power law) with low‑energy index α ≈ –1, high‑energy index β ≈ –2.3. |
| Radiation Mechanisms | • Synchrotron radiation in internal shocks.
• Photospheric (thermal) emission.
• Magnetic reconnection (ICMART) models. |
| Temporal Structure | Millisecond variability → constraints on the size of the emitting region (R ≲ c Δt Γ²). |
| Polarization | High linear polarization (up to ~30 %) in some bursts supports ordered magnetic fields. |
