Database updates :                  2. Mv and Teff values :             3. What else ?

Who: The OMP CorotSky Team          Prob: ~75% of the database, Mv      - Include spectrophotometry
When: Every month or so…                  relies on the « Parallax by   - Improve Teff, logg, [Fe/H] using

What: Add missing startypes                conversion (Allen)…
      Check catalogue contents
      Startypes in the Exo fields   What: Include V-I
