Public TESS data give 19 transit times for TOI-2525 b and c in 2023–2025
We measure 19 transit centers for the two known planets TOI-2525 b and c in public TESS data from 2023–2025. These 13 times for b and six times for c are absent from the two published timing tables checked in this study. We use all 27 public SPOC light curves at 120-second cadence returned for TIC 149601126. The median statistical errors are 4.9 minutes for b and 3.9 minutes for c. We require data across both transit edges and the nearby baseline. We also check older transits and insert 64 test transits into real flux. A two-planet model fits only 32 historical transit times. It fixes the published masses and orbit shapes, and adjusts four initial phase and period values. Its later residual RMS is 10.6 minutes for b and 11.0 minutes for c. The event search starts within 0.4 day of this model. These results apply to the accepted observed events. They do not test the full published orbit distribution or establish another planet. The package includes the source samples, file hashes, code, failed first-pass results, figures, and a separate repeat-run check.

This verified publication supplies all transit times, alternative later centers, and the conditional Newtonian predictions. We copy five input files without byte changes. We do not repeat its flux fits or orbit integration.
