Continuum images and primary beam images
One meta table per field, listing all the continuum images of this data version. This is useful to check whether a source is in the spatial coverage of our dataset.
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.
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 are also available at the COSMOS IRSA website: https://irsa.ipac.caltech.edu/data/COSMOS/images/a3cosmos/
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.
