• Two photometry catalogs per field: 

  • The blind photometry catalog A-COSMOS_blind*.fits contains blindly extracted ALMA sources with a peak flux signal-to-noise ratio of 5.4 or higher. The catalog also contains a column with a flag for sources which are identified as blended. 

  • 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. Flux density information is provided only for sources above the detection threshold (peak flux signal-to-noise ratio of 4.35). For undetected sources, information on image noise and beam sizes is provided so that upper limits can be determined. 

• One galaxy property catalog per field: 

  • The value-added 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.

• Other files available upon request: 

  • The catalog datatable_ID_RA_Dec_z_Mstar_SFR_sSFR_with_deltaGas.fits contains the galaxies in the Robust Galaxy Catalog with more columns including the molecular and total gas masses computed using the Hughes+2017 calibration ('Mgas' column) and other calibration methods.

  • The catalog datatable_ID_RA_Dec_z_Mstar_SFR_sSFR_with_SED_fluxes.fits contains one or multiple ALMA fluxes for each galaxy. FOBS and FSED are the observed and SED predicted fluxes at each ALMA wavelength.

  • Meta tables in FITS format for our ALMA images. This is useful to check whether a source is in the spatial coverage of our dataset. 

  • Our A3COSMOS/GOODSS Master Catalog, combining optical, near-IR, sub-mm and radio catalogs so as to identify unique sources for our prior-position-based photometry. 

• Notes:

  • The column names may be slightly different from our published ones, just let us know if you have any question.

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 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.
