CoRoT database (seismo)
Ground based preparation

• C0R0TSKY database 11,921 stars in CoRoT eyes
  with mVlt9.5
• High resolution spectroscopy strömgren
  photometry for 1500 stars (all stars with mVlt8
  some lt9.5)
• Data available in GAUDI (http//sdc.laeff.esa.es/g
  audi/)
• These data available catalogues used to
  determine fundamental parameters
• Accessible with COROTSKY tool

Effort supported by Laboratories and
Participating Countries
