Chilean Telescope Allocation Committee (CNTAC)

El Departamento de Astronomía de la Universidad de Chile (DAS) tiene el mandato de administrar el tiempo del telescopio chileno en las siguientes instalaciones: LCO , CTIO , SOAR , PROMPT , Mini-TAO , ASTE , NANTEN2 , QUIET , ACT y los Telescopios Nacionales en La Silla .

CNTAC is the interface between international telescopes and the Chilean astronomical community. The CNTAC also oversees the correct fulfillment of the agreements signed between the Universidad de Chile and international telescopes currently operating or planned to be operating in the country, and it is also responsible of the assignment of telescope time of these and other telescopes.

The Chair of the CNTAC is responsible of the correct operations of the CNTAC, and consults the Advisory Committee (AC) which is formed by representatives of the Chilean astronomical community.

The CNTAC issues a call for proposals twice a year with closing dates around April 15 and October 15 each year.

To this end, the Universidad de Chile twice a year organizes the Chilean Time allocation Committee (CNTAC). The CNTAC is formed by experts from the local community and from international observatories based in Chile.
