H-ATLAS All Potential Counterparts Catalog

Description

The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 600 deg^2 in five photometric bands - 100, 160, 250, 350 and 500 microns - with the Photoconductor Array Camera and Spectrometer (PACS) and Spectral and Photometric Imaging Receiver (SPIRE) cameras. H-ATLAS DR1 includes the survey of three fields on the celestial equator, covering a total area of 161.6 deg^2 and previously observed in the Galaxy and Mass Assembly (GAMA) spectroscopic survey. The data release main catalogue (HATLAS_DR1_CATALOGUE.FITS) contains only the 'best' candidate ID to each SPIRE source (where available). Most users will find in this catalogue everything they will need for their science purposes. A second catalogue is also available (HATLAS_DR1_CATALOGUE_ALLIDS.FITS), which contains all possible counterparts within the search radius of each SPIRE source, and provides the full LR statistics so that these may be independently analysed as the user wishes. To select only sources which have reliable optical IDs, a cut of Reliability#0.8 is recommended, although other cuts on Reliability or LR may be suitable for different purposes as discussed in Bourne et al. (2016).
