Abstract

We present the Mid-infrared stellar Diameters and Fluxes compilation infrared wavelengths (3-13 μm). It gathers data for half a millio stars, i.e. nearly all the stars of the Hipparcos-Tycho catalogue whos spectral type is reported in the SIMBAD data base. We cross-match 2 data bases to provide basic information, binarity elements, angula diameter, magnitude and flux in the near and mid-infrared, as well a flags that allow us to identify the potential calibrators. The catalogu covers the entire sky with 465 857 stars, mainly dwarfs and giants fro B to M spectral types closer than 18 kpc. The smallest reported value reach 0.16 μJy in L and 0.1 μJy in N for the flux, and 2 microarcsec fo the angular diameter. We build four lists of calibrator candidates fo the L and Nbands suitable with the Very Large Telescope Interferomete (VLTI) sub- and main arrays using the MATISSE instrument. We identif 1621 candidates for L and 44 candidates for N with the Auxiliar Telescopes (ATs), 375 candidates for both bands with the ATs, and 25 candidates for both bands with the Unit Telescopes (UTs). Predominantl cool giants, these sources are small and bright enough to belong to th primary lists of calibrator candidates. In the near future, we plan t measure their angular diameter with 1 per cent accuracy
