A3COSMOS is a project aiming at pipelining public archival ALMA data reduction, 
science-ready imaging and high-redshift source photometry in the COSMOS 2 square 
degree deep field (https://sites.google.com/view/a3cosmos). A3COSMOS is part of 
the wider COSMOS collaboration (http://cosmos.astro.caltech.edu). 

We release to the COSMOS IRSA repository ~1,900 ALMA continuum images and their 
corresponding primary beam images, which are produced by A3COSMOS as described 
by D. Liu et al. 2019 ApJS in press, and with version number 20180801. These 
images correspond to the public observations of 76 individual ALMA projects. 

We caution that the released continuum images are uncorrected for the primary 
beam attenuation, so that they have uniform RMS noise. However, scientific 
analysis should only be conducted after properly applying the primary beam 
correction using the primary beam images. 

We also provide a FITS format meta table file which contains useful 
information for each ALMA continuum image.
