TESS Sector 91 full-frame-image light curves at the position of HD 139139 (2025)

QLP light curves for TIC 70652803 (star A, HD 139139, Tmag 9.13) and TIC 1178179082 (star B, Tmag 11.93, 3.9″ away) at 200-second cadence, plus a TARS light curve for star A. TESS pixels are 21″, so the two stars are blended. Scattered light leaves about 14 clean days. With injected test dips, the data recover only 5–15 % of K2-like dips; see the injection-recovery run.
