Light-curve fitting results of GRB 230812B from various instruments.
| Instrument | Energy band | t − T0 | Γt |
|---|---|---|---|
| Fermi/LAT | 0.1–100 GeV | 10.2–647 s | 0.97 ± 0.58 |
| Fermi/GBM | 40–400 keV | 10.2–647 s | 1.62 ± 0.13 |
| Swift/XRT | 0.3–10 keV | 25–1400 ks | 1.31 ± 0.05 |
| Optical | r′ | 31–251 ks | 1.40 ± 0.03 |
Notes. Light curves from the instruments and the specific energy ranges listed in the first and second columns, respectively, are used for the fits. The fits are performed over the time intervals specified in the third column. A power-law model of the form F = F0(t − T0)−Γt, is used, with the best-fit temporal indices Γt reported in the last column. The corresponding best-fit models for each instrument are shown in Fig. 2.
