| Summary:
We present Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) maps of the
Cosmic Microwave Background temperature and polarization anisotropy at
arcminute resolution over three frequency bands centered on 98, 150 and 220
GHz. The maps are based on data collected with the AdvancedACT camera over the
period 2017–2022 and cover 19,000 square degrees with a median combined depth
of 10 uK arcmin. We describe the instrument, mapmaking and map properties and
illustrate them with a number of figures and tables. The ACT DR6 maps and
derived products are available on LAMBDA at
https://lambda.gsfc.nasa.gov/product/act/actadv_prod_table.html. We also
provide an interactive web atlas at
https://phy-act1.princeton.edu/public/snaess/actpol/dr6/atlas and HiPS data
sets in Aladin (e.g. https://alasky.cds.unistra.fr/ACT/DR4DR6/color_CMB).
