A Refined Orbital Period for TOI-4479 b from an Extended TESS Baseline: Transit-Timing Data

This dataset provides mid-transit times, O-C residuals, and per-transit fit diagnostics for 66 TESS transits of TOI-4479 b (TIC 126606859), derived from a joint transit fit to three TESS sectors (epochs -514 to +468, spanning a ~1138-day baseline between the first and last adopted mid-transit time). This dataset was created to support a refined transit ephemeris for the planet and a comparison against the literature (ExoClock) ephemeris. This dataset supports a manuscript in preparation, not yet submitted: Zhu, K. (2026, in prep.), "A Refined Orbital Period for TOI-4479 b from an Extended TESS Baseline," to be submitted to Research Notes of the AAS (RNAAS). This dataset is independently citable now via this record's DOI; the manuscript's citation will be added under Related works once available.
