Appendix of the paper entitled "GRB 240825A: Early Reverse Shock and Its Physical Implications"

Appendix of "Afterglow Observation Data and Spectral Fitting Results", In this appendix, we provide detailed information on the observation data and fitting results of afterglow. The observation data from various telescopes are listed as follows: SVOM C-GFT (Table A1), SVOM VT (Table A2), Swift UVOT (Table A3), HMT/T80 (Table A4), PAT17/ALT100C (Table A5), LCOGT (Table A6), VLT/NOT/GTC (Table A7), and Asiago/REM/ TNG/LBT/MISTRAL (Table A8). Figure A1 shows the corner plot of the posterior distributions for the afterglow fitting, and the corresponding parameter values, along with their prior ranges, are listed in Table A9.
