The CMT's 20 years of photometric data was studied to understand atmosphere extinction.[2] Up to 2003, 11 catalogs were published and it had been given various upgrades since its installation in 1984.[3]
The telescope is owned by the Danish Copenhagen University Observatory and was jointly operated under an international agreement with the Institute of Astronomy, Cambridge and the Real Instituto y Observatorio de la Armada.[3]
