The Agreement on Cooperation in Astrophysics, which was signed by eight European countries in La Palma on the 26th May 1979, confers on signatory organisations effective participation in the decision-making process by means of an International Scientific Committee (CCI).
There are three levels to the agreement:
- First level: documents signed by the respective governments.
- Second level: documents signed by the organisations in each country (signatory organisations).
- Third level: documents signed by the IAC and the Member Organisations.
