Correlated flux at 10 μm for each of the successful MIDI observations, color-coded following the baseline angle at which the observations were done. The baseline-0 observation (black point) corresponds to the average photometric flux of the observations. The full line shows a fit with the correlated-flux profile of an infinitesimally thin ring of angular diameter θ = 26.3 mas (reduced χ² = 1.54).
