A catalogue of stellar diameters and fluxes for mid-infrared
  interferometry
  We present the Mid-infrared stellar Diameters and Fluxes compilation
Catalogue (MDFC) dedicated to long-baseline interferometry at mid-infrared
wavelengths (3-13 mum). It gathers data for half a million stars, i.e. nearly
all the stars of the Hipparcos-Tycho catalogue whose spectral type is reported
in the SIMBAD database. We cross-match 26 databases to provide basic
information, binarity elements, angular diameter, magnitude and flux in the
near and mid-infrared, as well as flags that allow us to identify the potential
calibrators. The catalogue covers the entire sky with 465 857 stars, mainly
dwarfs and giants from B to M spectral types closer than 18 kpc. The smallest
reported values reach 0.16 muJy in L and 0.1 muJy in N for the flux, and 2
microarcsec for the angular diameter. We build 4 lists of calibrator candidates
for the L- and N-bands suitable with the Very Large Telescope Interferometer
(VLTI) sub- and main arrays using the MATISSE instrument. We identify 1 621
candidates for L and 44 candidates for N with the Auxiliary Telescopes (ATs),
375 candidates for both bands with the ATs, and 259 candidates for both bands
with the Unit Telescopes (UTs). Predominantly cool giants, these sources are
small and bright enough to belong to the primary lists of calibrator
candidates. In the near future, we plan to measure their angular diameter with
1% accuracy.
