Upper and middle panels: generalized Gaussian model fits (red) for the primary eclipses of the PA ≈ 3.96 days component (upper) and PB ≈ 4.94 days (middle) component of the quadruple candidate TIC 20938739. The black dots represent the TESS FFI data for Sector 51. The two eclipses have notably different shapes—one being more V-shaped and the other more U-shaped—yet the model fits both. Lower panel: phase-folded primary eclipses of the PA ≈ 3.08 days component of the quadruple candidate TIC 97642729 showing TESS FFI data for all available sectors (6, 33, 43, 44, 45, 72, and 87). Due to systematic effects, the apparent eclipse depths vary dramatically between different sectors.
