The Herschel-ATLAS data release 2. Paper II. Catalogs of far-infrared and submillimeter sources in the fields at the south and north Galactic poles

The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 660 deg(2) with the PACS and SPIRE cameras in five photometric bands: 100, 160, 250, 350, and 500 mu m. This is the second of three papers describing the data release for the large fields at the south and north Galactic poles (NGP and SGP). In this paper we describe the catalogs of far-infrared and submillimeter sources for the NGP and SGP, which cover 177.1 deg(2) and 303.4 deg(2), respectively. The catalogs contain 118,908 sources for the NGP field and 193,527 sources for the SGP field detected at more than 4s significance in any of the 250, 350, or 500 mu m. bands. The source detection is based on the 250 mu m map, and we present photometry in all five bands for each source, including aperture photometry for sources known to be extended. The rms positional accuracy for the faintest sources is about 2.4 arcsec in both R.A. and decl. We present a statistical analysis of the catalogs and discuss the practical issues-completeness, reliability, flux boosting, accuracy of positions, accuracy of flux measurements-necessary to use the catalogs for astronomical projects.
