ACT Data Products - Map Products for South 280 GHz

These files contain the Atacama Cosmology Telescope (ACT) temperature maps at 280 GHz. Production of the maps are described in Dunner et al (2013), "The Atacama Cosmology Telescope: Data Characterization and Mapmaking". The southern 280 GHz maps are described in Vargas et al (2023), "Atacama Cosmology Telescope: Extragalactic Point Sources in the Southern Surveys at 150, 220 and 280 GHz observed between 2008-2010"

The 1-way maps have been used for the study of millimeter emission in compact sources. The calibration of the maps was done using 4-ways via large and small modes. Caution is advised for studies of large modes in the 2008 map which does not have a flat transfer function

The units of the maps are ┬ÁK-CMB, expressing deviations from the average measured intensity as equivalent fluctuations in the CMB in units of micro-Kelvin.
