Atacama Cosmology Telescope (ACT) - Planck
The Atacama Cosmology Telescope (ACT) is a six-meter diameter telescope on Cerro Toco in the Atacama Desert of northern Chile. The ACT DR4 data release collected data from 2013 to 2016. ACT was upgraded to the AdvancedACT camera and conducted a 2017–2022 survey, corresponding to ACT DR6 data release, covering about 45% of the sky. At arcminute resolution, the surveys cover three frequency bands centered on 98, 150 and 220 GHz. The Atacama Cosmology Telescope took its final data in 2022 and has been decommissioned.
CADE deserves combinations of ACT and Planck data, in units of μK.
