Excess-only profiles of the ϵ Eri system at 34.8 μm after photospheric subtraction (nominal and ±6.3% the photospheric values. The PSF profile (normalized to the peak) is shown as the dashed line. The excess emission is resolved at 34.8 μm, which could arise from (1) a central broad ring with a width of ∼18 au, shown as the green line, or (2) one point source plus a ring peaked at 10 au (not shown, see details in Section 4.2).
