Notes. The Modified Julian Date (MJD), the seeing (in arcsecond), the coherence time τ0 (in millisecond) and the air mass (AM) are indicated. The last column lists the difference of the MATISSE diameter measurements of the calibrator θfit in comparison to JSDC catalogue θJSDC following the method from Robbe-Dubois et al. (2022) (see Sect. 2.2). T Mon is part of GTO program 104.D-0554(B). TT Aql(1) was used for the total flux and visibility in the N-band and TT Aql(2) for the calibration in the L and M band. For U Aql, only correlated flux was acquired due to its low brightness.
