Properties of the calibrators from the Mid-infrared stellar Diameters and Fluxes compilation Catalogue (MDFC) catalog (Cruzalèbes et al. 2019) used to calibrate the data.

Name Spectral Type Angular diameter [mas] L-band flux (#) [Jy] N-band flux (#) [Jy]
ν Tuc M4III 7.60 ± 0.75 244 ± 125 (3) 41 ± 1 (5)
η Scl M2/3III 6.30 ± 0.50 228 ± 66 (3) 41 ± 8 (5)
ω Cap M0IIIBa0.5 5.16 ± 0.50 248 ± 18 (3) 34 ± 4 (5)
λ Gru K3III 2.71 ± 0.03 88 ± 7 (3) 12 ± 4 (6)

Notes. We regrouped for each calibrator, the spectral type, angular diameter, the L-band and N-band flux and the associated error bar with the number of photometric observations used to estimate those quantities in between parentheses.
