Photometric 2-minute cadence PDCSAP time series of TIC 4897275 (HD 85426) in TESS sectors 21 (top panel) and 48 (bottom panel) are shown in grey, with 30-minute binned data overlaid in black. The transits of HD 85426 b are indicated by the blue box transits. The rise in flux shortly after BJD 2,459,630 is caused by a passing asteroid. The predicted conjunction time windows for planet c and planet candidate d are shaded in orange and violet, respectively. The width of these conjunction time windows was set to twice the predicted uncertainty.-- astro-ph.EP
