DR3 - Herschel ATLAS Data Release 3 covers the field centred at the South Galactic Pole (SGP). It contains the optical/near-IR counterparts to the Herschel sources in the SGP contained in the catalogue released in DR2. The counterparts have been found using the methods described in Ward et al. (2022). The methods are similar to those used to find the counterparts in the GAMA fields (DR1) and in the NGP (DR2), with a few additions. We now give estimates of the redshifts of the Herschel sources obtained by applying a template-fitting method to the Herschel fluxes. We also identify 5923 sources that are probably gravitationally-lensed sources.

DR2 - Herschel-ATLAS Data Release 2 covers two fields centered in the North Galactic Pole (NGP) and South Galactic Pole (SGP). The two fields are about 500 sq deg combined. The maps are described in Smith et al. 2017. The submillimter catalogues are described in Maddox et al. 2018 and includes 346894 sources in 5 photometric bands, which have a 4 sigma (including confusion noise) detection in any of the SPIRE bands. Furlanetto et al. 2018 describe optical identification from the SDSS DR10 catalogue and near-IR identification from a K-band deep catalogue obtained from UKIRT/WFCAM observations.

DR1 - Herschel-ATLAS Data Release 1 covers the three equatorial fields surveyed by the GAMA spectroscopic survey. The three fields are 161 sq deg combined, and are located around 09h, 12h and 14h in RA. The catalogue, described in Valiante et al. 2016, covers all three regions and includes 120230 sources in 5 photometric bands - 100, 160, 250, 350, 500 micron. It includes SPIRE sources which have a 4 sigma (including confusion noise) detection in any of the 250, 350 or 500 micron maps. It also provides a robust optical identification from the SDSS DR7/8 catalogue and spectroscopic redshifts from GAMA and SDSS (Bourne et al. 2016).
