MATISSE-calibrated squared visibilities in the L and M bands: U Aql, 7.02 d (a), η Aql, 7.17 d (b), β Dor, 9.84 d (c), ζ Gem, 10.15 d (d), TT Aql, 13.75 d (e), T Mon, 27.03 d (f), and U Car, 38.87 d (g). The thick orange curve is the visibility derived from the UD diameter of the star by SPIPS at the specific phase of the MATISSE observation. The dashed orange line represents the visibility derived for the star plus the CSE model by SPIPS (see Sect. 3.2). The dashed black curve is the fit of the UD angular diameter with the error derived from the bootstrap method (see Table 4). No model adjustments (labeled FIT) are presented for U Aql and TT Aql because these stars are mostly unresolved and are more affected by uncertainties in the absolute visibility scale. X Sgr data are impacted by a too short coherence time and thus are not presented.
