| Summary:

Two recent large data releases for the Atacama Cosmology Telescope (ACT),
called DR4 and DR5, are available for public access. These data include
temperature and polarization maps that cover nearly half the sky at arcminute
resolution in three frequency bands; lensing maps and component-separated maps
covering ~ 2,100 deg^2 of sky; derived power spectra and cosmological
likelihoods; a catalog of over 4,000 galaxy clusters; and supporting ancillary
products including beam functions and masks. The data and products are
described in a suite of ACT papers; here we provide a summary. In order to
facilitate ease of access to these data we present a set of Jupyter IPython
notebooks developed to introduce users to DR4, DR5, and the tools needed to
analyze these data. The data products (excluding simulations) and the set of
notebooks are publicly available on the NASA Legacy Archive for Microwave
Background Data Analysis (LAMBDA); simulation products are available on the
National Energy Research Scientific Computing Center (NERSC).
