Data version: 20180801 (included all ALMA data in COSMOS being public before date 2018-08-01)
Number of pointings: 1899 (beam_maj > 0.1 arcsec in COSMOS)
Areal coverage:
403.8 sq. arcmin, counting 2D Gaussian form pi/(4*ln(2))*primary_beam^2.
Or 280.0 sq. arcmin, counting 2D circular form pi*(primary_beam/2)^2.
Coverage map: see figure at right.
Area versus sensitivity: see figure below.
Data Release:
We published two photometry catalogs and one galaxy property catalog with our paper I in ApJS.
Please download the two photometry catalogs following this link on ApJS website: https://iopscience.iop.org/0067-0049/244/2/40/suppdata/apjsab42da_table4.tar.gz
And download the galaxy catalog following this link on ApJS website: https://iopscience.iop.org/0067-0049/244/2/40/suppdata/apjsab42da_table5.tar.gz
[Updates in May 2021] The ApJS links seem not accessible without visiting the journal webpage, alternatively, please find our catalogs here:

The blind photometry catalog A-COSMOS_blind.fits contains blindly extract ALMA sources with peak flux to rms ratio (S/N peak) greater than 5.40, which corresponds to a ~50% spurious fraction at that S/N and a ~12% cumulative spurious fraction for such a sample selection.
The prior photometry catalog A-COSMOS_prior.fits contains prior fitting of known optical/near-infrared/mid-infrared/radio sources in our COSMOS Master Catalog with S/N peak greater than 4.35, which also corresponds to a ~50% spurious fraction at that S/N and a ~8% cumulative spurious fraction for such a sample selection.
The galaxy catalog A-COSMOS_Robust_Galaxy_Catalog.fits contains only robustly detected galaxies with optical/near-infrared detections, so that each galaxy has a reasonably constrained, consistently fitted stellar mass, star formation rate and redshift.
There are a number of other very useful data:
Continuum images will be released soon at the COSMOS IRSA website: https://irsa.ipac.caltech.edu/data/COSMOS/overview.html or https://irsa.ipac.caltech.edu/data/COSMOS/images/a3cosmos/ (depending on IRSA schedule)
Galaxy SEDs (optical-to-mm-radio) are available upon request.
The combined COSMOS Master Catalog is available upon request.
The dust and dust-inferred molecular gas mass of each galaxy in the robust galaxy catalog are available upon request.
In addition, after the setup of the COSMOS IRSA repository, we will release a Python package to easily make cutouts and query sources.
